Magnetic field at point O will be

Magnetic field at point OO will be Magnetic field at point O will be

Options

  1. Aμ0I2R\frac{\mu_0 I}{2 R} interior
  2. Bμ0I2R\frac{\mu_0 I}{2 R} exterior
  3. C\frac{\mu_0 I}{2 R}(1−Iπ)\left(1-\frac{I}{\pi}\right) interior
  4. D\frac{\mu_0 I}{2 R}(1+Iπ)\left(1+\frac{I}{\pi}\right) exterior

Correct answer

A. μ0I2R\frac{\mu_0 I}{2 R} interior

Step-by-step solution

Magnetic field at the centre of circular loop B=μ0I2RB=\frac{\mu_0 I}{2 R} interior.
