Magnetism and the Motor Effect / Electromagnetic Induction

Question 1

what is the equation for the force on conductor?

Answer 1

force on conductor (N) = magnetic flux density (N/A m or T) x current(A) x length(m)

Question 2

what is the equation for the potential difference across primary coil?

Answer 2

potential difference across primary coil (V) x current primary coil (A) = potential difference across secendary coil(V) x current in secondary coil(A)

Question 3

What is the equation for electrical power?

Answer 3

electrical power(W) = current(A) x potential difference(V)
