Question

If we reverse direction of electric current, then direction of magnetic field will be:

• A. Reversed
• B. Remains same
• C. Becomes Tangent
• D. Becomes Normal

Answer 1

The correct option is A Reversed

we reverse direction of electric current, then direction of magnetic field will be reversed. If the direction of the current is reversed, the compass needle will move in the opposite direction because the polarity of the magnetic field has reversed.
