Answer:
Explanation:
Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. ... The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
Answer:
Explanation:
Kinetic energy generated = work done by force = force x displacement
= 3 x 7 = 21 J
Answer:
So magnetic field will be equal to 0.1144 T
Explanation:
We have given frequency f = 60 Hz
Maximum emf e = 5500 volt
Number of turns N = 150
Area 
Emf generated in ac generator is given 
For maximum emf 
So maximum emf will be equal to 
So magnetic field will be equal to 0.1144 T
