Question

Question 1

When an electric current flows through a copper wire AB as shown in Figure, the wire

(a) Deflects a magnetic needle placed near it

(b) Becomes red hot

(c) Gives electric shock

(d) Behaves like a fuse

Open in App

Solution

When the current is passed through the wire, it produces magnetic field in its surrounding. This magnetic field deflects the magnetic needle kept near the coil.
