Question

Needles N1,N2,N3 are made of a ferromagnetic, paramagnetic and a diamrignetic substahce respectively. A magnet when brought close to them will (A) attract all three of them (B) attract N1 and N2 strongly but repel N3 weakly (C) attract N1, strongly, N2 weakly and repel N3 weakly (D) attract N1, strongly, but repel N2,N3 weakly

Tardigrade Admin · Accepted Answer

Correct answer is (c) attract N1, strongly, N2 weakly and repel N3 weakly

Q. Needles $N_{1}, N_{2}, N_{3}$ are made of a ferromagnetic, paramagnetic and a diamrignetic substahce respectively. A magnet when brought close to them will

attract all three of them

attract $N_{1}$ and $N_{2}$ strongly but repel $N_{3}$ weakly

attract $N_{1}$ , strongly, $N_{2}$ weakly and repel $N_{3}$ weakly

attract $N_{1}$ , strongly, but repel $N_{2}, N_{3}$ weakly

Correct answer is (c) attract $N_{1}$ , strongly, $N_{2}$ weakly and repel $N_{3}$ weakly
