All my points answer me right now i have 3 inutes no guesses th assuming a current is flowing, what increases the strength of the magnetic field of a coiled electrical wire? select all that apply. straightening the wire changing the direction of the current flow adding more coils to the wire placing a metal bar within the coils stopping the current

Hello there!

Straightening the wire will "diffuse" the strength of the magnetic field.

changing the direction of the current will change the direction of the magnetic field.

adding more coils will increase the magnetic field because each coil can create a magnetic field of his own, and you can add them up.

Placing a metal bar within the coils the metal can be polarized by the electromagnetic field of the coil, wich will increment the magnetic field.

Stopping the current will stop the electromagnetic field generated by the coil.

so the answers are:

Adding more coils and placing a metal bar within the coils.

powerful computers now, not then
