COMEDK · Physics · 20. Magnetic Properties of Matter
A bar magnet is equivalent to
- A solenoid carrying current
- B circular coil carrying current
- C torroid carrying current
- D straight conductor carrying current
Answer & Solution
Correct Answer
(A) solenoid carrying current
Step-by-step Solution
Detailed explanation
