The induced current in a loop can be increased by:
Correct answer: D. all of these
- A. using a stronger magnetic field
- B. moving the loop faster
- C. replacing loop by a coil of many turns
- D. all of these
Explanation
D is the correct answer.The induced current in a loop can be increased by increasing the strength of the magnetic field, increasing the rate of change of the magnetic flux (which can be achieved by moving the loop faster), and increasing the number of turns in the coil (which increases the induced emf according to Faraday's law of electromagnetic induction).

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
