Answer:
when the direction of the Current changes.
Explanation:
Electromagnet refers to an iron ore wrapped around with a coil of wire, in presence of electric current. As it acts like a magnet, when current is passed through it.
The north & south poles of magnetic fields produced by such magnet, change with direction of current passed through it.
Sodium and potassium are positively charged ions called cations, and chloride and phosphate form negatively charged ions called anions. is true!
I believe you mean 6.02*10^7 but you want to shift the decimal 7 times to the right which would be 60200000 (:
Answer:
I would describe wave motion as “propagating oscillations” as a general phrase.
For something like water waves, I would say “water waves are oscillations of the surface of a body of water that propagate in a given direction.”
For electromagnetic waves I would say “An electromagnetic wave is an oscillating disturbance of the electric and magnetic fields that propagates through space.”
