Chapter 29: Q. 35 (page 832)

The right edge of the circuit in FIGURE EX29.35 extends into a 50mTuniform magnetic field. What are the magnitude and direction of the net force on the circuit?

Short Answer

Expert verified

The magnitude has 25mN and the direction is right.

Step by step solution

01

Step 1:Given Information

We have given the right edge of the circuit in the diagram extends into a 50mTuniform magnetic field.

02

Simplify

The current in the circuit is determined by Ohm's law

I=15v3Ω=5A,

and its direction is shown in the figure below. The field points into the plane of the circuit. By right-hand rule. WE determine that the magnetic force

F→=Il→×B→

points to the right and has the magnitude

F=IlB=15mN.

A proton in a cyclotron gains ∆k=2e∆vof kinetic energy per revolution, where ∆vis the potential between the dees. Although the energy gain comes in small pulses, the proton makes so many revolutions that it is reasonable to model the energy as increasing at the constant rate p=dK/dt=∆K/T, where Tis the period of the cyclotron motion. This is power input because it is a rate of increase of energy.

a. Find an expression for r(t), the radius of a proton's orbit in a cyclotron, in terms of m,e,B,P,andt. Assume that r=0at t=0.

Hint:Start by finding an expression for the proton's kinetic energy in terms of r.

b. A relatively small cyclotron is 2.0min diameter, uses a 0.55Tmagnetic field, and has a 400Vpotential difference between the dees. What is the power input to a proton, in W?

c. How long does it take a proton to spiral from the center out to the edge?

A Hall-effect probe to measure magnetic field strengths needs to be calibrated in a known magnetic field. Although it is not easy to do, magnetic fields can be precisely measured by measuring the cyclotron frequency of protons. A testing laboratory adjusts a magnetic field until the proton's cyclotron frequency is 10.0MHz. At this field strength, the Hall voltage on the probe is0.543mVwhen the current through the probe is0.150mA. Later, when an unknown magnetic field is measured, the Hall voltage at the same current is1.735mV. What is the strength of this magnetic field?
