Question

Magnetic field lines in closed loops​

Answer 1

Answer:

Isolated magnetic poles or monopoles do not exist. The magnetic fields is a continuous loop because north and south poles always come together. Magnetic field lines are continuous, forming closed loops without beginning or end. ... Electric field lines end and begin on positive and negative charges which can be separated.

Answer 2

Answer:

1.The field is tangent to the magnetic field line.

2.Field strength is proportional to the line density.

3.Field lines cannot cross.

4.Field lines are continuous loops.
