A neutral conductor (or dielectric) experiences a torque, but no net force, when placed in a uniform electric field. It does experience a net force in a non-uniform field.
When an electrically neutral object is suspended in a uniform electric...
When a magnetic field is applied perpendicular to a conductor carrying current, a potential difference is observed between points on opposite sides of the conductor. This happens because the magnetic field deflects the moving electrons...
What it shows: Using the classical description of the motion of a spin in an external magnetic field, the demonstration helps visualize NMR in the time domain. The nuclear magnet and its classical vector model are represented by a spinning ball with...
A physical pendulum finds stability in its inverted position when driven at the proper frequency and amplitude combination.
The physical pendulum is a 45 cm x 2 cm x 6 mm (1/4") strip mounted on a ball-bearing pivot and can rotate 360 degrees...
A collimated beam of Cathode rays can be deflected by a magnetic field.
This Crookes tube has an anode and cathode at opposite ends of a cylindrical tube, with a horizontal slit near the cathode and a vertical fluorescent...

Maltese cross obstacle and fluorescing glass show that electrons in a Crookes tube travel in straight lines and are affected by magnetic fields.
Cathode rays in a Crookes tube are seen to travel in straight lines by casting a sharp shadow of...
Image on black and white television is deflected by a magnet, not unlike the Maltese Cross.
What it shows:
The television is basically a sophisticated cathode ray tube. The electron beam in the TV is influenced by magnetic fields in the same way as in...
A current carrying wire in a magnetic field experiences a force at right angles to both the field and current directions. The wire will jump up or down, depending upon the current direction.
