Question : 6
Total: 15
(a) Name the poles P , Q , R S a
1 ∕ 2 + 1 ∕ 2 + 1 = 2
OR
When is the force experienced by a current-carrying straight conductor placed in a uniform magnetic field.
1 + 1 = 2
(i) Maximum;
(ii) Minimum?
(b) State the inference drawn about the direction of the magnetic field lines on the basis of these diagrams.
OR
When is the force experienced by a current-carrying straight conductor placed in a uniform magnetic field.
(i) Maximum;
(ii) Minimum?
Solution:
(a) P = Q = R = S =
(b) On the basis of these diagrams, we can say that magnetic field lines always leave the north pole of a magnet and enter into the south pole. Hence, direction of magnetic field remains from north to south.
OR
(i) When the current is perpendicular to the magnetic field.
(ii) When the current is parallel to the magnetic field.
