A strip of metal moves through a uniform magnetic field of strength 0.6 T. If it has a length of 2 m and moves at a speed of 4 m/s, what is the induced emf?
💡 Hint: Identify each component in the formula.
Two parallel rails in a horizontal track are connected at one end. A conducting bar moves along the rails perpendicular to a magnetic field. If the resistance in the circuit created is 2 ohms and the induced emf is measured at 10 V, calculate the current flowing through the circuit.
💡 Hint: Apply the relationship between voltage, current, and resistance.
