A wire with a current of 1.31 A is to be formed into a circular loop of one turn. If the required value of the magnetic field at the center of the loop is 10 µT, what is the required radius?

The required radius is 2.62 cm

Explanation:

Given;

magnitude of current in wire, I = 1.31 A

magnetic field strength, B =  10 µT

Applying Biot Savart equation;

where;

r is the radius of the wire

μ₀ is constant = 4π x 10⁻⁷ Tm/A

I is the current in the wire

B is the magnetic field strength

Substitute the given values and calculate the radius

Therefore, the required radius is 2.62 cm

explanation:

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
