The amount of energy of a photon is proportional to the frequency.
<span>The advantage of using an electromagnet rather than a regular magnet is that an electromagnet is stronger and you can control the power of the magnet. </span>
The type of ball is independent, as it doesn’t affect the experiment.
I believe it's Gamma Rays. Hope my answer helped :)
Answer:
The induced voltage is
Explanation:
From the question we are told that
The number of turns is
The diameter is
The initial magnetic field is
The final magnetic field is
The time taken is
The radius is mathematically evaluated as
substituting values
Generally the induced emf is mathematically represented as
Where is the change in magnetic flux of the wire which is mathematically represented as
=>
Here
since the axis of the coil is parallel to the field
Where A is the cross-sectional area of the coil which is mathematically represented as
So the induced emf
Here we substituted the values of
