Why are electromagnets stronger than permanent magnets? Because the amount of current and the number of coils in the copper wire can increase the strength of an electromagnet while a…
I learned this today. Some metals are nonmagnetic because the magnetic poles of the atoms within them point in different directions and are weakly repelled by both poles of the…
I learned this today. An MRI works by causing the protons in the hydrogen nuclei in our bodies to align with a magnetic field and then disrupts them with a…
