A square coil ${10^{ - 2}}{m^2}$ area is placed perpendicular to a uniform magnetic field of intensity ${10^3}Wb/{m^2}$. The magnetic flux through the coil is
A magnet is brought towards a coil (i) speedly (ii) slowly then the induced e.m.f./induced charge will be respectively
The direction of induced e.m.f. during electromagnetic induction is given by
In a coil of area $10\;c{m^2}$ and 10 turns with a magnetic field directed perpendicular to the plane and is changing at the rate of ${10^8}$gauss/second. The resistance of the coil is 20 ohm. The current in the coil will be
As shown in the figure, a magnet is moved with a fast speed towards a coil at rest. Due to this induced electromotive force, induced current and induced charge in the coil is $E,\;I$ and $Q$ respectively. If the speed of the magnet is doubled, the incorrect statement is Question Image
A coil having 500 square loops each of side 10 cm is placed normal to a magnetic flux which increases at the rate of 1.0 tesla/second. The induced e.m.f. in volts is
When a magnet is pushed in and out of a circular coil C connected to a very sensitive galvanometer G as shown in the adjoining diagram with a frequency $\nu $, then Question Image
A coil of area $100c{m^2}$ has 500 turns. Magnetic field of $0.1\;weber/metr{e^2}$ is perpendicular to the coil. The field is reduced to zero in 0.1 second. The induced e.m.f. in the coil is
A 50 turns circular coil has a radius of $3\;cm$, it is kept in a magnetic field acting normal to the area of the coil. The magnetic field $B$ increased from 0.10 tesla to 0.35 tesla in 2 milliseconds. The average induced e.m.f. in the coil is
A coil having an area $2{m^2}$ is placed in a magnetic field which changes from $1Wb/{m^2}$to $4Wb/{m^2}$in a interval of 2 second. The e.m.f. induced in the coil will be
