Induced electromotive force

Electricity and Magnetism Level 1

The above diagram is a uniform magnetic field with intensity \(4\text{ T}.\) The direction of the magnetic field is downwards through the plane on which a conducting wire and a \(20\text{ cm}\) metal stick are placed as shown above. If we drag the metal stick on the conducting wire to the right at a constant speed of \(1 \text{ m/s},\) then what is the current intensity flowing in the resistor with a resistance of \(2 \text{ }\Omega?\)
