Magnetic interactions

Variant i Interactive tutorial lecture   Other Variants Dynamics first      

Students are given practice in: relating magnetic fields to currents, using the right-hand rule, and relating the behavior of a magnetic compass to external magnetic fields.

Topics   Electricity and magnetism / Magnetism: fields, representations, vectors, bar magnet, compass, current-carrying wire, forces, Lorentz force, magnetic fields, and right-hand rules

Tutorial details

Section I: Magnetic forces on charged particles

In this section, students apply the right-hand rule for magnetic force on charged particles in uniform fields. Each question provides two of the necessary vector directions (for velocity, magnetic field, or force) and students are asked to find the direction of the third.

Section II: Magnetic force on a current-carrying wire

Students apply the right-hand rule to make predictions about the magnetic force by a bar magnet on a current carrying wire. After making each prediction, they observe the associated demonstration and resolve any inconsistencies between their predictions and observations.

Section III: Magnetic compasses

Students explore the magnetic fields of a bar magnet and a current carrying wire by predicting the orientation of a compass placed at different points in each magnetic field.

Prerequisites

Students should have studied single-battery circuits and the magnetic field produced by a bar magnet.
