Question

The tangent drawn to the magnetic field line at a point gives

• A. magnetic flux
• B. current
• C. direction of the magnetic field
• D. charge

Hint:

The tangent to a magnetic field line always represents the direction of the field at that point.

Answer 1

The Correct Option is C

The tangent to a magnetic field line at any point gives the direction of the magnetic field at that point. It helps to determine the orientation of the magnetic field in space. Magnetic flux is related to the area and strength of the magnetic field, current is related to the flow of charge, and charge refers to the fundamental property of matter. Thus, the correct answer is the direction of the magnetic field.
