Explain the ratlionship betwwen each word 5 points?

Explain the ratlionship betwwen each word 5 points?



1.current-electromagnet



2.motor-geneator



3.electron- magnetism



4.magnetosphere- aurora



5.magnet-magnetic domain



Explain the ratlionship betwwen each word 5 points?virus scan



1) current can create an electromagnet.



2) motors are generators



3) direction of flow of electrons defines the direction of magnetic flux



4) magnetosphere causes the aurora



5) magnet determines magnetic domain



Explain the ratlionship betwwen each word 5 points?anti virus scan



(1)the flow of the current in a wire casue a magnetic field to be produced around the wire so the wire can be ued as a kind of electromagnet



(2)they work in different ways:



motor :its axis spins when acurrent moves in the file of this axis which was put inside the magnetic field of a magnet



(the magnetic field produced by the current caused the file to spin)



generator,it's the opposite ,acurrent is produced in its file ,which was put inside a magnetic field, because of the motion of this file



(3)electrons are the constituent of the current so the motion of the electron equivalent to the current so it produces a magnetic field around the electron



(4) i don't know



(5) i don't know
