Magnetic Field of the Earth The Earth's magnetic field is similar to that of a bar magnet tilted 11 degrees from the spin axis of the Earth. The problem with that picture is that the Curie temperature of iron is about 770 C . The Earth's core is hotter than that and therefore not magnetic.

Contents: Electric Field vs Magnetic Field As the amount of current flowing increases, the level of magnetic field increases. Magnetic fields are measured in milliGauss (mG). An electric field occurs wherever a voltage is present. Electric fields are created around appliances and wires wherever a voltage exists.

- This you see as the north pole forming near the north pole of the solenoid. Like poles repel, unlike poles attract is kind of a misleading analogy(I find it strange that I realized this after reading your question). What actually is happening is that the tiny magnetic dipoles inside the magnetic material(a bar of iron, for example) align with the direction of the magnetic field.

List of electromagnetism equations Lorentz force on a charged particle (of charge q) in motion (velocity v), used as the definition of the E field and B field. Here subscripts e and m are used to differ between electric and magnetic charges. The definitions for monopoles are of theoretical interest, although real magnetic dipoles can be described using pole strengths. There are two possible units for monopole strength, Wb (Weber) and A m (Ampere metre).

What are electromagnetic fields? In contrast to electric fields, a magnetic field is only produced once a device is switched on and current flows. The higher the current, the greater the strength of the magnetic field. Like electric fields, magnetic fields are strongest close to their origin and rapidly decrease at greater distances from the source.

- Magnetic and electric fields exist nearly everywhere, and the following is a brief description of what these fields are, how they are created, and what effects they produce. The concept of an electric field arose when electrons were observed to repel other electrons but attract protons.he second effect is that a changing magnetic field can create an electric field. This is the basis of power transformers and electric power generation. One coil of wire (or one electromagnet as in Fig. 5) is placed close to another.

What is Polarity? The pole with more electrons is said to have negative polarity. The pole with fewer electrons then has a positive polarity. When the two poles are connected by a wire, electrons flow from the negative pole toward the positive pole. This flow is called an electric current.

Wandering of the Geomagnetic poles Magnetic poles are defined in different ways. They are commonly understood as positions on the Earth's surface where the geomagnetic field is vertical (i.e., perpendicular) to the ellipsoid. These north and south positions, called dip poles, do not need to be (and are not currently) antipodal.

Electric Motors & Generators: Converting Between Electrical and Mechanical Energy While the generator and the vacuum (or any other device powered by a motor) may serve different functions, they are actually two sides of the same coin. In fact, they are the same device! In an electrical motor, the input is electricity and the output is mechanical power. Contrary to this, a generator takes mechanical power and outputs electricity. In both cases, electricity is flowing - just in a different direction! Electromagnetism. Both motors and generators run because of something called electromagnetic induction. Discovered by Michael Faraday, this is when a voltage is induced by a changing magnetic field. With electromagnetic induction, an electric current can be produced in a coil of wire by moving a magnet in or out of that coil, or by moving the coil through the magnetic field. Either way, voltage is created through motion.

- Some facts about magnets include: 1  the north pole of the magnet points to the geomagnetic north pole (a south magnetic pole) located in Canada above the Arctic Circle. 2  north poles repel north poles. 3  south poles repel south poles.4  north poles attract south poles.5  south poles attract north poles. magnet is any material or object that produces a magnetic field. This magnetic field is responsible for the property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets.

magnetic pole The north pole of a magnet is the pole out of which magnetic lines of force point, while the south pole is the pole into which they point. The Earth's geomagnetic north and south poles are, in fact, magnetically the opposite of what their names suggest; this is why the north end of a compass needle is attracted to the geomagnetic north pole.

- Below is a magnet with 8 poles. This magnet has 8 poles - 4 North and 4 South, or 4 pole-pairs. A compass in the vicinity of a magnet will always point along a tangent to one of the magnetic field lines.hese places are the poles. The magnetic field lines tend to be closest together there. This is why, if you break a magnet in half, you will still have a North pole and a South pole, since the lines enter one magnet, then exit it, then enter the next magnet, then exit it, before it goes back to the first magnet again.

Static Fields 1 A magnetic field is a force field created by a magnet or as a consequence of the movement of the charges (flow of electricity). The magnitude (intensity) of a magnetic field is usually measured in Tesla (T or mT).  The term static refers to a situation where the fields do not vary with time. Static electric and magnetic fields are two distinct phenomena, both characterized by steady direction, flow rate and strength (thus a frequency of 0 Hz). A static electric field (also referred to as electrostatic field) is created by charges that are fixed in space;

Contents: Electric Field vs Magnetic Field edit Force. The electric field is actually the force per unit charge experienced by a non moving point charge at any given location within the field, whereas the magnetic field is detected by the force it exerts on other magnetic particles and moving electric charges.

What is the different between magnetic poles and electric charge? Answers. Best Answer: Main difference is that magnetic poles do not exist without both north and south poles together, whereas electric charges, such as plus and minus, can exist alone. So you can never find a magnetic monopole, i.e. magnetic north or magnetic south by itself. You always find a magnetic dipole. But you can find an electron or a negatively charged object, as well as a proton or a positively charged object.

Electric and Magnetic Fields (EMF) The magnetic fields result from the flow of current through wires or electrical devices and increase in strength as the current increases. Magnetic fields are measured in units of Gauss (G) or Tesla (T). Gauss is most commonly used in the United States and Telsa is the internationally accepted term. Unlike an electric field, a magnetic field is only produced when the current is flowing.
