Question

1. A particle with a charge of 0.8 C is moving at right angles to a uniform magnetic field with a strength of 0.6 T. The velocity of the charge is 620 m/s. What is the magnitude of the magnetic force exerted on the particle?
N

4. Two long parallel wires, each carrying a current of 8 A, lie a distance of 10 cm from each other. What is the magnetic force per unit length exerted by one wire on the other?

N/m

If the distance between the two wires is tripled, what is the new force per unit length?
N/m

Explanation / Answer

A)F=q*V*B=0.8*620*0.6=297.6 N

B)F/l=uo*i1*i2/(2*pi*r)...

F/l=0.128*10^-3 N/m


C)F1*r1=F2*r2.....

F2=F1/3=0.0426*10^-3 N/m
