Faraday’s Laws According to the Faraday’s first law, whenever the amount of magnetic flux linked with a circuit changes, an emf is induced in it. Induced current is determined by the rate at which the magnetic flux changes.Mathematically, the magnitude of the induced emf in a circuit is equal to the rate of change of magnetic flux through the circuit.Induced emf `prop` Rate of change of magnetic fluxA copper disc of radius 0.1 m is rotated about its centre with 20 rev/s in a uniform magnetic field of 0.1 T with its plane perpendicular to the field. The emf induced
A coil has an area of 0.05 m2 & it has 800 turns. It is placed perpendicularly in a magnetic field of strength , `4xx10^(–5) Wb/m^(-2)`. It is rotated through `90^o` in 0.1 sec. The average emf induced in the coil
In a region of uniform magnetic induction `B = 10^(-2)` tesla, a circular coil of radius 30 cm and resistance ` π^2` ohm is rotated about an axis which is perpendicular to the direction of B and which forms a diameter of the coil. If the coil rotates at 200 rpm the amplitude of the alternating current induced in the coil
A magnetic field `2xx 10^(-2) T` acts at right angles to a coil of area `200 cm^2` with 25 turns. The average emf induced in the coil is 0.1 v when it removes from the field in time t. The value of t
A compass needle free to turn in a horizontal plane is placed at the centre of circular coil of 30 turns and radius 12 cm. The coil is in a vertical plane making an angle of 45° with the magnetic meridian. When the current in the coil is 0.35 A, the needle points west to east.(i) Determine the horizontal component of the earth’s magnetic field at the location.(ii) The current in the coil is reversed, and the coil is rotated about its vertical axis by an angle of 90° in the anticlockwise sense looking from above.
