Question

A bar magnet having centre O has a length of 4 cm: Point P1 is in the broad side-on and P2 is in the end side-on position with O P1=O P2=10 metres. The ratio of magnetic intensities H1 and H2, respectively, at P1 and P2 is (A) H1: H2=16: 100 (B) H1: H2=1: 2 (C) H1: H2=2: 1 (D) H1: H2=100: 16

Magnetic intensity in end side on position is twice that in the broad side on position.

Q. A bar magnet having centre $O$ has a length of $4 c m$ : Point $P_{1}$ is in the broad side-on and $P_{2}$ is in the end side-on position with $O P_{1} = O P_{2} = 10$ metres. The ratio of magnetic intensities $H_{1}$ and $H_{2}$ , respectively, at $P_{1}$ and $P_{2}$ is

$H_{1} : H_{2} = 16 : 100$

$H_{1} : H_{2} = 1 : 2$

$H_{1} : H_{2} = 2 : 1$

$H_{1} : H_{2} = 100 : 16$

Magnetic intensity in end side on position is twice that in the broad side on position.

Q. A bar magnet having centre O has a length of 4cm : Point P1​ is in the broad side-on and P2​ is in the end side-on position with OP1​=OP2​=10 metres. The ratio of magnetic intensities H1​ and H2​, respectively, at P1​ and P2​ is

H1​:H2​=16:100

H1​:H2​=1:2

H1​:H2​=2:1

H1​:H2​=100:16

Magnetic intensity in end side on position is twice that in the broad side on position.

Q. A bar magnet having centre $O$ has a length of $4 c m$ : Point $P_{1}$ is in the broad side-on and $P_{2}$ is in the end side-on position with $O P_{1} = O P_{2} = 10$ metres. The ratio of magnetic intensities $H_{1}$ and $H_{2}$ , respectively, at $P_{1}$ and $P_{2}$ is

$H_{1} : H_{2} = 16 : 100$

$H_{1} : H_{2} = 1 : 2$

$H_{1} : H_{2} = 2 : 1$

$H_{1} : H_{2} = 100 : 16$
