Given :
- Number of loops = 300
- Length of the coil = 20 cm
- Magnetic field = 0.7 T
- EMF induced = 210 V
To find :
- Velocity of the coil to produce a peak output of 210 V.
Formula to be used :
where,
- denotes emf induced
- L denotes length of the coil
- B denotes the magnetic field
Solution :
In the question it is mentioned that there are 300 loops so we need to modify the formula and multiply it with N which is equal to number of loops.
Therefore,
Substituting the given values
Verification :
Let's verify our result with the formula.
Hence Verified !~
