A system having two opposite magnetic poles separated by a distance 'd' is called as a magnetic dipole. If 'm' is magnetic pole strength and 'Ɩ' is the length of the magnet.

Magnetic materials are the materials which can be made to behave as a magnets. When these materials are kept in an external magnetic field, they will create a permanent magnetic moment in it.

An ohmic contact is a non-rectifying contact which obeys ohm's law i.e., V=IR. The resistance of the ohmic contact should always be low i.e., conductivity should be large.

It is used to determine whether the material is p-type or n-type semiconductor. (i.e.,) if RH is negative then the material is n-type. If the RH is positive then the material is p-type.

Measurement of conductivity will not determine whether the conduction is due to electron or holes and therefore will not distinguish between p-type and n-type semiconductor.

In conductors, when temperature is increased, the lattice vibration increases, which causes increased scattering and hence the mobility and conductivity decreases.
