Vedclass · Answer

(B) The correct matching is as follows:$(A)$ High retentivity: Permanent magnets require high retentivity so that they do not lose their magnetic properties easily. Thus,$(A) \rightarrow (iv)$.$(B)$ High resistivity: Materials with high resistivity are used to decrease eddy current losses in transformers and other electrical devices. Thus,$(B) \rightarrow (iii)$.$(C)$ Low coercivity: Soft magnetic materials,which have low coercivity,are used in devices like telephone diaphragms and electromagnets. Thus,$(C) \rightarrow (i)$.$(D)$ Negative susceptibility: Diamagnetic substances are feebly repelled by a magnetic field and have a small negative susceptibility. Thus,$(D) \rightarrow (ii)$.Therefore,the correct match is $A-(iv), B-(iii), C-(i), D-(ii)$.

Assertion: We cannot think of a magnetic field configuration with three poles.
Reason: $A$ bar magnet does exert a torque on itself due to its own field.

$A$ bar magnet has a total length $2l = 20$ units and the field point $P$ is at a distance $d = 10$ units from the centre of the magnet. If the relative uncertainty of length measurement is $1\%$,then the uncertainty of the magnetic field at point $P$ is
