Which statement is not true about electromagnets? A. The electric current in an electromagnet generates a magnetic and electric field surrounding the wire.
B. Electromagnets can be turned off and on. When they are turned off the magnetism disappears.
C. Increasing the voltage of the electromagnet will cause the current to increase, thus increasing the strength of the electromagnet.
D. None of the statements are false

insects!

explanation:

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
