The production of an electric current by a changing magnetic field is known as electromagnetic induction.
The phenomenon when the current is produced due to changing magnetic field is given by Faraday.
And this phenomenon is called the electro-magnetic induction or magnetic induction since the electricity is generated due to the fluctuations or variance in the magnetic field.

Answer:
The speed of the proton is 4059.39 m/s
Explanation:
The centripetal force on the particle is given by;
The magnetic force on the particle is given by;
The centripetal force on the particle must equal the magnetic force on the particle, for the particle to remain in the circular path.
where;
r is the radius of the circular path moved by both electron and proton;
⇒For electron;
⇒For proton
The speed of the proton is given by;
Therefore, the speed of the proton is 4059.39 m/s
Answer:
Hiiiiiiii........where r u frm??
Answer:
4.71m/s
Explanation:
Given parameters:
Distance covered = 40.5m
Time taken = 8.6s
Unknown:
Speed = ?
Solution:
The speed of Samantha is the distance divided by the time taken.
Speed =
Now insert the parameters;
Speed = = 4.71m/s
Answer:
The angular speed of the reel is 11.33 rad/s
Explanation:
Given
The fisherman takes t = 8.4 s to wind distance x = 2.9 m into a circle radius of r = 3 cm = 0.03 m
Than the tangencial speed equals the change in the distance to the time
v = =
Knowing the tangencial velocity is proportional to the radius r and the angular velocity
v = r*w
w =
