Answer :
The magnetic area is parallel to the direction of the contemporary within the twine. electric costs produce electric-powered fields and magnets produce magnetic fields.
A magnetic discipline is a vector discipline that describes the magnetic impact on moving electric expenses, electric-powered currents, and magnetic materials. A moving fee in a magnetic subject reviews a force perpendicular to its own velocity and to the magnetic field.
The magnetic area is the area round a magnet that has magnetic pressure. All magnets have north and south poles. contrary poles are attracted to every different, even as the identical poles repel each different. when you rub a bit of iron along a magnet, the north-looking for poles of the atoms inside the iron line up in the equal path.
