Question

a electron is to travel in a uniform magnetic field at a constant speed (2 E6 per second ) in a circle of radius in a circle of radius 1 centimeter . Calculate the magnitude of the required magnetic field. a electron is to travel in a uniform magnetic field at a constant speed (2 E6 per second ) in a circle of radius in a circle of radius 1 centimeter . Calculate the magnitude of the required magnetic field. a electron is to travel in a uniform magnetic field at a constant speed (2 E6 per second ) in a circle of radius in a circle of radius 1 centimeter . Calculate the magnitude of the required magnetic field.

Explanation / Answer

Equation for magnetic field in terms of radius r and velocity v is

r = m*v/(q*B)

m = mass of electron

q = charge of electron

B = magnetic field

B = (9.1*10^-31*2*10^6)/(1.6*10^-19*1*10^-2) = 1.1375*10^-3 T
