alexira [117]

Answer:

E = q V B     describes the electric field induced

E Proportional to V B

while the magnet is pushed into the coil the induced field (B) will increase (consider 1 turn of the coil)

If V is constant the E-field will increase due to increasing B and the galvanometer will deflect accordingly

When V drops to zero the deflection must again be zero

So one would see a blip due to the deflection of the galvanometer

Note that as V increases the galvanometer will deflect one way and then as V drops to zero the deflection will be opposite (drop to zero when V is zero)

B always increases to a constant value because of the properties of the magnet.

Explanation:

A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.

Some of the names of the basic quantities include:

  1. Mass, denoted by the symbol 'm', with S.I. unit 'kg'
  2. Length, denoted by symbol 'l', with S.I. unit 'm'
  3. Time, denoted by symbol 't', with S.I. unit 's'
  4. Current, denoted by 'I', with S.I. unit 's' 'A'
  5. Temperature, denoted by 'T', with S.I. unit 'K'
  6. Amount of substance, denoted by 'n', with S.I. unit 'mol'
  7. Luminous Intensity, denoted by 'Iv', with S.I. unit 'cd'

  • A basic quantity is chosen arbitrarily.
