Why does a current carrying conductor produce a magnetic field around it?
Why does a current-carrying conductor always have magnetic field around it?
Why does a changing magnetic field induce a current? Why does a magnet produce a magnetic field? Why current is flowing through the conductor? Why are magnetic fields produced? Why do magnets produce magnetic field like the way they do? As Frecuncy increase, magnetic flux inside conductor? How and why is electric potential continually decreasing in a conductor carrying current? What is a magnetic field? How magnetic field is produced by electric field? What is magnetic field? A current flows in a conductor from west to east. What is the direction of the magnetic field at a point below the conductor? How is a magnetic field created? What is the direction of induced magnetic field due to changing electric field? What is the direction of induced electric field due to changing magnetic field? Does a charged particle moving through a magnetic field always experience force? Why the magnetic field lines are normal to the surface in case of ferromagnets? In a magnetic crane, a powerful electromagnet is used to lift up the iron material. But when we pass a current through a conductor & bring iron filings near it, they are set in a concentric manner, instead of clinging the conductor. Why? What is the main difference between magnetic and electric fields? What is magnetic? What's the difference between electric field and magnetic field? In a magnetic crane, a powerful electromagnet is used to lift up the iron material. But when we pass a current through a conductor & bring iron filings near it, they are set in a form of concentric circles, instead of clinging to the conductor. Why? What's the difference between a magnetic field and an electromagnetic field? What is the difference between electric and magnetic fields? Why isn't the force of a magnet limited to the magnet itself, how can it form a field? What is the magnetic field due to an electromagnet at a point that is not along its axis? What will be the force on a current carrying conductor if all the parameters are doubled? How can one show that the magnetic field due to an infinitely long current carrying conductor at a point near its end is given by B = (μ0) I/ (4πa) using Ampere's Circuital Law (preferably) or Biot Savart's Law? Why is there a magnetic field for the Earth? Why does conventional current always flow in the opposite direction of electrons? What is the difference between magnetic flux and magnetic field?
