Practice NEET UG Electromagnetic Induction in the app →A bar magnet pushed into a coil at rest causes the galvanometer needle to kick because:A copper rod of length $0.5$ m slides at $4$ m/s perpendicular to a $0.2$ T field. The motional EMF is:A coil of self inductance $0.2$ H carries $5$ A. The magnetic energy stored is:A bar magnet falling into a vertical copper tube on the lab bench drops more slowly than in free fall because:Faraday's law of induction states:Lenz's law states that the induced current direction is such that it:Motional EMF induced across a rod of length L moving with velocity v perpendicular to a field B is:Self-inductance L of a coil is the proportionality between:The self-inductance of a long solenoid of length ℓ, area A, with n turns per unit length is approximately:Energy stored in an inductor of self-inductance L carrying current I is:Mutual inductance M between two coils relates the EMF induced in coil 2 to the current in coil 1 as:A transformer works on the principle of:Eddy currents are reduced in transformer cores by:A magnetic flux through a coil changes from 4 Wb to 1 Wb in 0.3 s. The average EMF induced is:A coil of inductance 0.5 H carries a current changing at 4 A s⁻¹. The induced EMF is:A bar magnet is dropped through a vertical conducting ring. The magnet:Maxwell's correction to Ampère's law introduced:An LC circuit oscillates with angular frequency ω equal to:When a rod moves perpendicular to a magnetic field at constant velocity, the FREE charges in the rod experienc
