Magnetism and matter Questions
The meter-bridge wire AB shown in figure is 50 cm long. When AD = 30 cm, no deflection occurs in the galvanometer. Find R.
Two geometrically similar magnets having same mass but magnetic moments M₁ and M₂ (M₁>M₂) are taken and vibrate in a vibration magnetometer with their like poles together and unlike poles together. If the ratio of their time periods in both cases res
A galvanometer has resistance of 30 Ω and a current of 1 mA is needed to give full scale deflection. The resistance required to be connected in series to convert it into a voltmeter of range 1 V will be
A standard bar magnet has a magnetic moment M and pole strength m. If it is sliced longitudinally into three identical thin magnets, what will be the magnetic moment and pole strength of each piece?
