Replace the wire. now remove one of the wires touching the voltage source. What happened ?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?

Ajoint produces movement when its angle decreases. which type of movement is it?

Why are nonmetals more likely to react with eachother by sharing electrons
