Question

Mohit made an electromagnet ‘A’ by coiling 50 turns of wire over an iron nail. Rani also made an electromagnet ‘B’ by coiling 100 turns over a similar iron nail. Which electromagnet will attract more pins? ​

Answer 1

Answer: The magnetic effect is openly depended on the number of turns of wire on the electromagnet. Therefore, Rani's electromagnet will attract additional pins as it has an additional number of turns of wire on it.

So, Rani's electromagnet is a strongest electromagnet. ​
