Answer 2

Answer:

magnetic field can be pictorially represent by magnetic field lines, the properties of which are as following

1. the field is tangent to magnetic field line.

2. field strength is proportional to line density.

3. magnetic field lines form closed loops .

4. the behave like stretched elastic rubber string .
