Question

Long straight wire carries a current of pie ampere the magnetic field due to it will be 5 x10^-5weber/m^2 at what distance from the wire

Answer 1

Hello dear,

◆ Answer -

x = 1.257 cm

◆ Explaination -

# Given -

B = 5×10^-5 wb/m²

I = π A

# Solution -

Magnetic field at distance x from magnetic field is given by formula -

B = μI / 2πx

x = μI / 2πB

x = (1.257×10^-6 × π) / (2 × π × 5×10^-5)

x = 1.257×10^-2 m

x = 1.257 cm

Therefore, distance of wire from magnet must be 1.257 cm.

Thanks dear...
