On Friday Alaina, Gemma, and I did the electromagnets lab. We had to build an electromagnet and we used a computer to measure the magnetic strength. We made the electromagnet with a nail, a wire, battery, and tape. We used a vernier magnetic field sensor to measure the magnetic strength. We winded a wire around the nail and attached the ends of the wire to the battery with tape. The first time we wound the wire around the nail three times. We then held the nail over the magnetic sensor to measure the magnetic force. Then we wound the wire different amounts of times until we got to 19 winds. We discovered that the more winds the more magnetic strength. The battery and wire also got hotter when we added more winds.
I'm not sure how this relates to Mission to Mars. This had to do with energy because the sensor was measuring magnetic force.
