Explore the ways to change the magnetic field, and measure its direction and magnitude around the magnet. Explore the interactions between a compass and bar magnet. Discover how you can use a battery and coil to make an electromagnet.
30 mar 2024 · The gaussmeter method is suitable for teaching middle school and high school students about magnetic fields. Here's how to start using one: Set the maximum voltage to be read at 10 volts DC.
A beam of electrons travels at 6.0×10 6 m/s through a uniform magnetic field of 6.5×10 − 1 T at right angles to the field. How strong is the force acting on each electron?
The strength of the magnetic field is shown by the spacing of the magnetic field lines. If the magnetic field lines are close together then the magnetic field will be strong. If the magnetic field lines are far apart then the magnetic field will be weak.
Let's practice problems to understand what the closeness of magnetic field lines at a point tells us about the strength of the magnetic field there.
What is needed to make an electromagnet? And what can increase the strength of the magnetic field created by an electromagnet? Explore these questions and more with our Electromagnet simulation.
The student is expected to: (G)investigate and describe the relationship between electric and magnetic fields in applications such as generators, motors, and transformers. In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Magnetism, as well as the following standards: (5) Science concepts.
