Question

(5 pt.) A charged particle enters a uniform magnetic field. What happens to the kinetic energy to the particle? 4. (a) it decreases (b) it increases (c) it stays the same (d) it changes with the direction of the velocity (e) it depends on the direction of the magnetic field (5 pt.) By Faraday's law of magnetic induction, the instantaneous EMF induced in a circuit containing N tightly wound loop equals the time rate of change of MAGNETIC FLUX through the circuit, E Then, how emf can be induced? 5. dt (a) Increase/decrease B-field strength (b) Change area of loop inside B-field (c) Rotating coil in the field (d) All of above

Explanation / Answer

4) kinetic energy remains the same

because the force is always perpendicular to the velocity vector so work is zero that is kinetic energy is same

5) flux = BAcos(theta)

emf can changes due to the

change in field

change in area

change in rotation

so answer is all the above
