Dear student
Properties of the material of an electromagnet :
(1) The material should have low retentivity so that it gets demagnetised easily.
(2) For the electromagnet to be very strong, it should have a high value of saturation magnetisation.
(3) It should have low coercivity .
(4) Hysteresis loss should be small. It should not be heated up during magnetisation and demagnetisation.
Properties of the material of a permanent magnet :
(1) It should have high retentivity so that it remains magnetised in the absence of the magnetising field.
(2) It should have high saturation magnetisation.
(3) It should have high coercivity so that it does not get demagnetised easily.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
