Question

EXPLAIN WHY THE MAGNETIC FIELD SHOWS DEFLECTION IN OERSTED'S EXPERIMENT.
CBSE class 10

Answer 1

Explanation:

The needle deflects one side. When key is taken out and current in wire becomes zero, needle returns back to its initial position (S – N). This shows that a magnetic field is associated with an electric current. When direction of current in wire is reversed, direction of deflection of needle is also reversed.
