Apr 2, 2022 · Like magnetic poles repel, and unlike magnetic poles attract each other. Therefore the north pole of the compass needle points to the south pole of the bar magnet, and vice …

A magnetic field is caused by a moving electric charge correct? The moving electric charge causes an increase in the electric field in front of it and a decrease in the electric field in back …

Electric current I I produces around itself magnetic field strength " H H → " (also called as "Magnetic field intensity") regardless the type of the surrounding medium. "Magnetic Flux …

Jun 11, 2013 · I was wondering if there is any way to stop the magnetic field, without having the insulator turned into magnet. Let me present this as a simple case, there is a magnet to the left …

Dec 6, 2021 · Making magnetic field lines go from north to south is just a convention. An equally valid convention could have been magnetic field lines going from south to north. The magnetic …

Jun 11, 2022 · The ideal magnetic dipole For the ideal magnetic dipole it's exactly the same, only a little different. ;) Take a current loop of given magnetic dipole moment m and reduce its size …

Aug 11, 2021 · The magnetic field outside an infinitely long AC solenoid is NOT zero, as shown by explicit calculation from Maxwell's equations by Abbot & Griffiths, American Journal of Physics …

Aug 25, 2018 · The rule is called Lenz's Law. You already appear to know how to determine the direction of the magnetic field due to a current in a loop, which is part of the answer. What …
