when a magnet is moved into the coil of wire shown, there is a small reading on the sensitive meter. Which change would increase the size of the reading?
Correct answer: A. Moving the magnet faster
- A. Moving the magnet faster
- B. Pilling the magnet out
- C. Pushing in the S-pole
- D. Unwinding some of the turns of wire
Explanation
Induced emf can be increased by I. Using large no. of turns 2. Using stronger B 3. Moving the loop faster

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.
