Total questions: 20
Worksheet time: 34mins
The magnetic field oriented into the page has an initial field strength of 5 Tesla into the page. It changes to 2 Tesla into the page. What is the direction of the induced current?
Clockwise
Counterclockwise
A conductive loop moves downward into the magnetic field as shown in the diagram. Which way will the induced current flow in the conductive loop?
Clockwise
Counterclockwise
Can you produce current in a wire with a magnet that is sitting still?
Yes; having a magnet near a wire is enough to excite the electrons
No; the magnetic field has to be changing to excite the electrons
No; magnets cannot create electricity
The magnetic field oriented out of the page has an initial strength of 6 Tesla. Over time the field out of the page increases to 10 Tesla out of the page. What is the direction of induced current in the loop?
CW
CCW

A wire carries a current, creating a magnetic field around itself as shown. The current in the wire is:
Directed to the right
Directed to the left
Equal to the magnetic field
In the same direction as the magnetic field
The magnetic field oriented out of the page has an initial strength of 7 Tesla. Over time the field out of the page decreases to 2 Tesla out of the page. What is the direction of induced current in the loop?
Clockwise
Counterclockwise

A small object with a charge of 𝑞 = +3.0 μ𝐶 and a mass 𝑚 = 2.0 × 10-6 𝑘𝑔 enters a magnetic field of magnitude 𝐵 = 0.20 𝑇 directed into the page, as shown in the figure below. If the speed of the object is 1000 𝑚/𝑠, the object’s acceleration at the moment it enters the field is most nearly ______.
zero because the velocity is perpendicular to the magnetic field
300 m/s2 toward the bottom of the page
300 m/s2 toward the top of the page
600 m/s2 toward the bottom of the page
600 m/s2 toward the top of the page
Uniform magnetic and electric fields exist between the two oppositely charged parallel plates shown in the figure below. An electron travels horizontally between the plates. Assuming gravitational effects to be negligible, which of the following diagrams shows a combination of electric and magnetic field directions that will allow the electron to travel un-deflected?
Four small particles are seen moving through an area with the magnetic field going out of the page. Which of the following statements is consistent with the diagram?

Two particles are positive while one is negative
Two particles are negative while one is positive
You can only ascertain that all are charged
