Question

6. What is the magnetic field of a magnet? How can the magnetic field lines of a bar magnet
be observed?​

Answer 1

Answer:

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.

The magnetic field lines of a bar magnet can be traced out with the use of a compass. The needle of a compass is itself a permanent magnet and the north indicator of the compass is a magnetic north pole. ... Unlike magnetic poles attract, so the north indicator of the compass will point toward the south pole of a magnet.
