Refer to the image below and state how the magnetic field pattern indicates regions where the magnetic field is stronger outside the magnet? What happens to the magnetic field when the current in the circuit is reversed? CBSE 2024 Science Class 10 Sample Question Paper Solved.
Answer

The magnetic field strength is more in the region where the field lines are crowded. This indicates that the field strength is maximum near the poles and it reduces as we go away from the poles.

When the direction of current in the circuit is reversed the direction of the magnetic field is also reversed.
