Test: Magnitude of The Generated or Induced EMF - Question 3
Save

If a conductor 0.2m long moves with a velocity of 0.3m/s in a magnetic field of 5T, calculate the emf induced.

Detailed Solution for Test: Magnitude of The Generated or Induced EMF - Question 3

The formula for induced emf is: emf=Blv. Substituting the values of B, l and v from the question, we get emf=0.3V.

Test: Magnitude of The Generated or Induced EMF - Question 4

What is emf?
Detailed Solution for Test: Magnitude of The Generated or Induced EMF - Question 6

Electromotive force is not actually a force. It is basically a voltage. It is the voltage developed by any source of electrical energy.

Test: Magnitude of The Generated or Induced EMF - Question 7
Save

An E.M.F. can be induced by _________
Detailed Solution for Test: Magnitude of The Generated or Induced EMF - Question 7

The dot product of magnetic field vector and area vector.
emf=BAcos(theta), hence if either of the three, that is, magnetic field, area or angle changes, thee emf will change.

Test: Magnitude of The Generated or Induced EMF - Question 8
Save

 The emf induced in a coil having N turns is?
Detailed Solution for Test: Magnitude of The Generated or Induced EMF - Question 8

The emf induced in a coil having N turns is, e=N*phi/t. This is because, the emf in a single coil is the flux linkage per unit time, that is, phi/t. Hence the flux induced in N turns is N*phi/t.

Test: Magnitude of The Generated or Induced EMF - Question 9
Save

The total number of magnetic field lines passing through an area is termed as ________
Detailed Solution for Test: Magnitude of The Generated or Induced EMF - Question 9

The number of magnetic flux lines per unit area is the magnetic flux, because flux is the number of field lines per unit area.

Test: Magnitude of The Generated or Induced EMF - Question 10
Save

What is the consequence of motor effect?
Detailed Solution for Test: Magnitude of The Generated or Induced EMF - Question 10

Motor effect is when a current carrying conductor in a magnetic field experiences a force, hence its consequence is electromagnetic induction.
