Question

The fact that current was associated with a magnetic field was discovered by

• A. Oersted
• B. Maxwell
• C. Faraday
• D. Ohm

Answer 1

The correct option is A

Oersted

Explanation for the correct answer:

Option (A) Oersted

1. The electric current-carrying wire produces a magnetic field around it.
2. When a magnetic compass is brought near a current carrying wire, it deflects showing the presence of magnetic field.
3. This was the experiment performed by Oersted and therefore known as Oersted law.

Explanation for incorrect options:

1. Maxwell discovered the existence of an electromagnetic wave.
2. Faraday discovered the laws of Electromagnetic Induction.
3. Ohm discovered Ohm's law for electric current.
