Question

A solenoid carrying current behaves like an electromagnet. To determine poles of the solenoid which rule is helpful:

• A. Right Hand Thumb Rule
• B. Fleming's Left Hand Rule
• C. Lenz's Law
• D. Faraday's Law

Answer 1

The correct option is A Right Hand Thumb Rule

Right Hand Thumb Rule gives direction of magnetic field lines around a current carrying conductor.

Magnetic field lines start from north pole and ends at south pole outside a magnet(or electromagnet).

Using above two properties, poles of solenoid can be found.
