In this lab, you can explore motional emf. The red rod can slide without friction on the blue rails. A constant force (in red) is applied on the rod to the right. We might think that that would result in motion with constant acceleration to the right, but that's not what we see.
LAB
In this lab, observe a loop pass through a region of the magnetic field. Note that the magnetic field is directed into the screen on the left side, and out of the screen on the right side. Predict what the graphs will look like before you view them.
LAB
In this lab, you can click and drag the dot at the center of the magnet to move the magnet left or right. The graphs show the magnetic flux through each loop of the coil, as a function of time, as well as the emf induced in the coil as a function of time.
LAB
In this lab, watch a magnet pass through a coil at a constant velocity. The graphs show the magnetic flux through each loop of the coil, as a function of time, as well as the emf induced in the coil as a function of time. You can reverse the direction of the magnet and observe the graphs.
LAB
This lab shows a simulation of direct current motor, which is simply a current loop that rotates in a magnetic field because of the torque applied to the loop by the field.
LAB
In this lab, you can explore the force between long straight current-carrying wires. The simulation shows a cross-section through the wires.
LAB
In this lab, you can see the graph of the magnetic field on the x-axis as a function of position. Click-and-drag the wires to move them left or right.
LAB
The lab shows the magnetic field near two long-straight current-carrying wires.
If the wire is drawn in red, the current is directed out of the screen.
If the wire is drawn in blue, the current is directed into the screen.
LAB
This lab allows you to explore a cyclotron, which is a very compact particle accelerator. In the D-shaped sections (these are called dees) there is a uniform magnetic field that makes the positively charged particle follow a path that is a half circle.
