Can you create electricity with magnetism?

Yes. That's how a magneto on a small lawn mower creates the spark for the spark plug. A magnet passes a coil and energizes the coil to produce electricity.

Step-by-step explanation:

Magnetic fields can be used to make electricity
The properties of magnets are used to make electricity. Moving magnetic fields pull and push electrons. ... Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current

The area of the triangle is about 7.18 square meters.

To find the area when given two sides and the included angles, we can use the following formula.

Area = AB(SinC)/2
Area = 4(8.5)(Sin25)/2
Area = 14.369/2
Area = 7.18

The area is about 7.18 square meters.
