Homework Answers
Whenever the magnetic flux linked with the coil changes, an end will be induced in it.
So correct option are
1. rotating the coil in a magnetic field so that it's axis is sometimes aligned and sometimes misaligned with the magnetic field.
2. Bringing the magnet into the solenoid from far away.
3. Holding the coil at rest in a fluctuating magnetic field.

PLEASE ANSWER ALL PARTS a. A circular coil of wire with 7 loops and a radius of 0.041 m is placed inside a solenoid. The coil is aligned so that the normal to the coil is parallel to the magnetic field in the solenoid. The solenoid consists of 40000 loops of wire and is 0.18 m long. Initially a current of 0.5 A runs through the solenoid. The current is increased to 4.5 A over a period of 4.1 s....

Magnetism 1. (4) An unknown particle travelling at a velocity of 2.20x106 m/s to the right as seen by an observer, enters a region that has an electric field of magnitude 750 V/m pointed away from the observer. Ignore gravity for this question. (a) What is the direction and magnitude of the perpendicular magnetic field which would best cancel out the effect of the electric field so that the particle passes through undeflected? (b) If while travelling 0.200 m, with...

What do the positive helium ions do for the e / m apparatus? Choose the most complete, best answer. They help focus the electron beam and they emit photons which allow the beam to be seen. They help focus the electron beam. They emit photons which allow the beam to be seen. They get hot and glow. They are there so that the bulb does not implod They are there only when the electrons are not orbiting, otherwise, they move...
