Question

what happens to the magnetic field if the current is reserved?​

Answer 1

Answer:

The magnetic field generated is always perpendicular to the direction of the current and parallel to the solonoid. Hence if we reverse the current the direction of magnetism also reverses. In other words the magnetic poles gets reversed (North pole becomes south pole and the south pole becomes the north pole).

Answer 2

ANSWER;

The magnetic field generated is always perpendicular to the direction of the current and parallel to the solonoid.
