How is a magnetic field generated when a current flows through a conductor? As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field. The strength of this field is called the magnetic moment. The motion of an electric charge producing a magnetic field is an essential concept in understanding magnetism. The magnetic moment of an atom can be the result of the electron's spin, which is the electron orbital motion and a change in the orbital motion of the electrons caused by an applied magnetic field.

- because the magnetic field direction indicated by the compass deflection when the circuit. is closed is a superposition of the Earth’s magnetic field and the wire’s, the deflection. angle is not as simple as the 1/r dependence of the field due to the wire alone [4, pg. 527].

Electromagnetic induction In more visual terms, the magnetic flux through the wire loop is proportional to the number of magnetic flux lines that pass through the loop. When the flux through the surface changes, Faraday's law of induction says that the wire loop acquires an electromotive force (EMF). The most widespread version of this law states that the induced electromotive force in any closed circuit is equal to the rate of change of the magnetic flux enclosed by the circuit:

Magnetic Force on a Current-Carrying Wire Magnetic Force on a Current-Carrying Wire. The magnetic force on a current-carrying wire is perpendicular to both the wire and the magnetic field with direction given by the right hand rule. If the current is perpendicular to the magnetic field then the force is given by the simple product: Force = Current x Length x B-field.

Magnetic fields and how to make them The magnetic field from a such current-carrying wire actually wraps around the wire in circular loops, decreasing in magnitude with increasing distance from the wire. To find the direction of the field, you can use your right hand.If you curl your fingers, and point your thumb in the direction of the current, your fingers will point in the direction of the field. The magnitude of the field at a distance r from a wire carrying a current I is given by:Currents running through wires of different shapes produce different magnetic fields.Consider a circular loop with a current traveling in a counter-clockwise direction around it (as viewed from the top).lectric fields come from charges. So do magnetic fields, but from moving charges, or currents, which are simply a whole bunch of moving charges. In a permanent magnet, the magnetic field comes from the motion of the electrons inside the material, or, more precisely, from something called the electron spin.

Right-Hand Rules: A Guide to finding the Direction of the Magnetic Force 1) the charge is moving relative to the magnetic field, 2) the charge's velocity has a component perpendicular to the direction of the magnetic field. The Right-Hand Rules apply to positive charges or positive (conventional) current.

Introduction to Magnetism and Induced Currents For example, if a loop of wire is placed in a magnetic field so that the field passes through the loop, a change in the magnetic field will induce a current in the loop of wire. A current is also induced if the area of the loop changes, or if the area enclosing magnetic field changes.

Magnetic field Using the right hand and pointing the thumb in the direction of the moving positive charge or positive current and the fingers in the direction of the magnetic field the resulting force on the charge points outwards from the palm. The force on a negatively charged particle is in the opposite direction.

Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field.he magnetic field created by an electromagnet is proportional to both the number of turns in the winding, N, and the current in the wire, I, hence this product, NI, in ampere-turns, is given the name magnetomotive force.

Introduction to Magnetism and Induced Currents The changing magnetic field caused by the material's motion induces a current in the coil of wire proportional to the change in field. If a 0 is represented, the magnetic field does not change between the two domains of a bit, so no current is induced as the magnetic material passes the coil.

The compass is showing you what direction the magnetic field is in, so you can use the right hand rule to work out whether the current is flowing north to south or south to north.

Blown Head Gasket Symptoms The main cause of blown head gaskets is the overheating of an engine. This can cause a great deal of damage not just to the head gasket but the cylinder head itself can crack, warp or swell. The pistons can swell in the cylinder and seize, valve components can seize as can bearings.he main cause of blown head gaskets is the overheating of an engine.

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.

This magnetic field can be visualized as a pattern of circular field lines surrounding a wire. One way to explore the direction of a magnetic field is with a compass, as shown by a long straight current-carrying wire in . Hall probes can determine the magnitude of the field.
