Which of the following is true about magnetic dampening? Conductors experience magnetic dampening as it enters or leaves a uniform magnetic field. None of the other four statements are true about magentic dampening. Conductor is slowed as it enters the field but sped up as it exits it. Magnetic dampening is independent of the speed of the conductor. Magnetic dampening is greatest when the conductor is completely in a uniform magnetic field. Acircular loop of radius 0.30 m is placed...

MAGNETIC FIELDS SUMMARY You will measure how the magnetic field, B, produced by a coil varies with the current, I, in the coil. From your measurements, you w calculate the permeability constant Ho. Lastly you w use a magnet to induce a voltage in the coil. THEORY The magnetic field Batthe center of a circular coil (solenoid) of radius R with N turns that carries a current...

Magnetic field region There is a uniform magnetic field of magnitude B= 1.6T and directed out of the plane of the screen in the region shown. Outside this region the magnetic field is zero. A rectangular loop o.2 mby 0.6 m and of resistance 42 and mass 8 grams is being pulled into the magnetic field by an external force as shown. - What is the direction (CW or CCW) of the current induced in the loop? Calculate the magnitude...

A uniform magnetic field is at right angles to the plane of a wire loop. The field decreases by 0.16 Tin 3.0×10−3 s and the magnitude of the average emf induced in the loop is 79 V . A) What is the area of the loop? (in m^2) B) What would be the value of the average induced emf if the field change was the same but took twice as long to decrease? (in Volts)
The apparatus below is submerged in a uniform, constant magnetic field
The apparatus below is submerged in a uniform, constant magnetic field, B. A conducting bar moves to the left at a constant speed v on two conducting rails joined as shown. As a result of the bar moving through this constant magnetic field, a current I is induced in the indicated direction. Which one of the following directions is that of B? a) Toward the right b) Toward the left c) Parallel to the long axis of the bar d) Into...

A charged particle is moving in a uniform, constant magnetic field. Which one of the following statements concerning the magnetic force exerted on the particle is false It does no work on the particle. It increases the speed of the particle. It changes the velocity of the particle. It can act only on a particle in motion. It does not change the kinetic energy of the particle.

This problem explores how a current-carrying wire can be accelerated by a magnetic field.
This problem explores how a current-carrying wire can be accelerated by a magnetic field. You will use the ideas of magnetic flux and the EMF due to change of flux through a loop. Note that there is an involved follow-up part that will be shown once you have found the answer to Part B.A.) A conducting rod is free to slide on two parallel rails with negligible friction. At the right end of the rails, a voltage source of strength...
