Consider at time t= 0, a uniform a magnetic field (directed out of the page) B = 6.0tis turned on as shown below. The loop has radius 20.0 cm and it is connected to a resistance R = 5.0 92 shown as below. What is the magnitude of the induced emf and the current in the loop at t=2.5 sec? Is the direction of induced emf clockwise or counterclockwise in the loop? M R = 592
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. A circular current loop with radius of 0.100 m is located in the...

A circular loop of wire with radius r= 0.0480m and reistance R = 0.160 Ω is in a region of spatially uniform magnetic field, as shown in the figure. The magnetic field is directed out of the plane of the figure. The magnetic field has an initial value of 8.00 T and is decreasing dB/ dt = -0.680 T a) Is the induced current in the loop clockwise or counterclockwise? b) What is the rate at which electrical energy is being dissipated...

A circular coil of radius 5 cm has 50 turns of wire. The uniform magnetic field directed into the page/screen (see the figure below) is linearly increased in magnitude form 0 to 0.8 T. What time interval for this increase is needed to induce in the coil emf = 0.25 V? What is the direction of the induced emf (clockwise/counterclockwise)? Which law do we use?

Use the following to answer question 5-6 The figure shows a uniform, 3 T magnetic field that is normal to the plane of a conducting, circular loop with a resistance of 1.5 ohms and a radius of 0.024m. The magnetic field is directed out of the paper as show. Note: the area of the non-circular portion of the wire is considered negligible compared to that of the circular loop 5. If the magnetic field is doubled in 0.4s what is...
12. (5 pt.) If the circular conductor undergoes thermal expansion while it is in a uniform magnetic field, a current will be induced clockwise around it (lind). Which statement is correct? A. Bind is out of the page, so the magnetic field is directed out of the page B. Bindis out of the page, so the magnetic field is directed into the page C. Bina is into the page, so the magnetic field is directed into the page D. Bind...
Consider a conducting loop placed on a horizontal plane in a region of uniform magnetic field directed downward. If the magnitude of the magnetic field begins to decrease, what will the direction of the induced current in the loop be? Select one: a. Clockwise, so that the magnetic field of the loop is upward b. Clockwise, so that the magnetic field of the loop is downward c. Counterclockwise, so that the magnetic field of the loop is upward d. Counterclockwise,...
