Answer:
Explanation:
Given:
- mass of the one ion,
- mass of another ion,
- velocity of projection into the magnetic field,
- charge on each ion,
- magnetic field,
We have, force on a charged particle due to the perpendicular magnetic field:
............................(1)
Force on mass moving in a circular trajectory
...............................(2)
where "r" is the radius of trajectory.
from eq. (1) & (2)
putting the values for the condition 1:
putting the values for the condition 2:
∵The charges have covered a semicircular path from the point of entrance,
∴ their difference in the radius will give their distance from each other.
Answer:
Magnitude of the induced emf is 11.62 V
Explanation:
Given:
No. of turns of the circular coil, N=185
Radius, R=4.50 cm=0.045 m
No. of turns of solenoid per meter(m), n=350
a=12.5 A
b=2.10
Now,
To determine the emf induced in the coil at t = 1.50 s:
The given equation is:
Now,
Now, substituting the respective values:
Now,
where,
A=Area=
Thus,
Answer: because when you remove the battery, the the magnet no longer has electricity flowing through it, therefore the magnetic field disappears. Thats why its called a temporary magnet
