Magnetism And Electromagnetism: Units
Muhtasari
Magnetism and electromagnetism bring together electrical quantities you already know - current, voltage, power - with newer ones such as the tesla for magnetic flux density. Keeping these units straight is essential when you move between circuit calculations and electromagnetic force problems.
This lesson collects the key units for the Magnetism and Electromagnetism section in one place, clarifies what each one measures, and gives you short practice exercises so you can recognise and apply them with confidence on exam day.
Malengo
- Use the following units: ampere (A), volt (V) and watt (W)
