Today, Earth's magnetic field is losing approximately 7 percent of its strength every 100 years. If the strength of Earth's magnetic field at its surface is 0.5 gauss today, what will it be 100 years from now?

It would be 0.5-0.5*0.07=0.5-0.035=0.465 gauss.

In 100 years, the strength of Earth's magnetic field will decrease from 0.5 gauss to approximately 0.465 gauss due to a 7 percent loss in strength. This is calculated by determining the decrease amount and subtracting it from the initial strength. Therefore, the future strength will be 0.465 gauss.
