Question

how can a magnetic field in a circular loop be tested at the centre

Answer 1

Answer:

Field at Center of Current Loop

B = x 10^ Tesla = Gauss. B = x 10^ Tesla = Gauss. The current used in the calculation above is the total current, so for a coil of N turns, the current used is Ni where i is the current supplied to the coil. The Earth's magnetic field at the surface is about 0.5 Gauss.

Answer 2

Hi buddy

Here is your answer

Field at Center of Current Loop

Field at Center of Current LoopB = x 10^ Tesla = Gauss. B = x 10^ Tesla = Gauss. The current used in the calculation above is the total current, so for a coil of N turns, the current used is Ni where i is the current supplied to the coil. The Earth's magnetic field at the surface is about 0.5 Gauss

The magnetic field strength at the center of a circular loop is given by B=μ0I2R(at center of loop), where R is the radius of the loop. RHR-2 gives the direction of the field about the loop

Hope it help you
