Face of coil having clockwise current:
Correct answer: B. Behaves like the south pole
- A. Behaves like the north pole
- B. Behaves like the south pole
- C. Becomes a magnet of varying poles
- D. Does not behave like a magnet
Explanation
A current-carrying loop or coil functions as an electromagnet. The direction of current flow determines the polarity of the magnetic field produced. Using the clock face rule: if you look at the face of the coil with current flowing in a clockwise direction, it behaves like a south pole. Conversely, if the current flows anti-clockwise, it behaves like a north pole. Therefore, the correct answer is that the face of the coil with a clockwise current behaves like the south pole.Option A is incorrect because clockwise current results in a south pole, not a north pole. Option C is incorrect because the polarity does not vary; it remains constant as long as the current direction is constant. Option D is incorrect because a current-carrying coil always behaves as a magnet, thus possessing magnetic properties with defined poles.

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.
