Question

State the factors on which the magnitude of magnetic field at the centre of a circular coil depends.

• A. i) Strength of electrons in the coil (Directly Proportional ) ii) Number of turns in the coil (Directly Proportional) iii) Area of the coil (Inversely Proportional)
• B. i) Strength of electrons in the coil (Directly Proportional) ii) Number of turns in the coil (Inversely Proportional) iii) Radius of the coil (Inversely Proportional)
• C. i) Strength of current in the coil (Directly Proportional) ii) Length of the coil (Directly Proportional) iii) Area of the coil (Directly Proportional)
• D. i) Strength of current in the coil (Directly Proportional) ii) Length of the coil (Inversely Proportional) iii) Radius of the coil (Directly Proportional)
• E. i) Strength of current in the coil (Directly Proportional) ii) Number of turns in the coil (Directly Proportional) iii) Radius of the coil (Inversely Proportional)

Answer 1

The correct option is E

i) Strength of current in the coil (Directly Proportional)

ii) Number of turns in the coil (Directly Proportional)

iii) Radius of the coil (Inversely Proportional)

Magnitude of magnetic field at the centre of a circular coil depends on

i) Strength of current in the coil (Directly Proportional)

ii) Number of turns in the coil (Directly Proportional)

iii) Radius of the coil (Inversely Proportional)
