Two magnetic field lines never intersect...

Two magnetic field lines never intersect each other. Why?

Text Solution

Verified by Experts

Intersection of magnetic field lines at a point means that the compass needle would point towards two directions at that point, which is not possible.

A magnetic dipole is under the effect of two magnetic fields inclined at 75^(@) to each other. One of the fields has a magnitude of 1.5xx10^(-2) T. The magnets come to stable position at an angle of 30^(@) with the direction of above field. The magnitude of other field is :

`(15)/(2sqrt(2)) xx 10^(-2)T`

`(1.5)/(sqrt(2)) xx 10^(-2)T`

`1.5xxsqrt(2)xx10^(-2)T`

`1.5xx10^(-2)T`.

A magnetic dipole is acted upon by two magnetic fields which are inclined to each other at an angle of 75^(@) . One of the fields has a magnitude of sqrt(2) xx 10^(-2) T. The dipole attains stable equilibrium at an angle of 30^(@) with this field. What is the magnitude of the order field ?

0.01 T

0.02 T

0.03 T

0.04T

`(15)/(2sqrt(2))xx10^(-2)T`

`(15)/sqrt(2)xx10^(-2)` T

`1.5xxsqrt(2)xx10^(-2)` T

`1.5 xx10^(-2)` T
