a. How does using more loops of wire in an electromagnet affect the strength of the magnetic field? b. Write two or three sentences to identify the energy conversion that takes place in an electric motor and to describe how electromagnetism is involved.
a) do you think adding more loops makes the strength higher or lower?
I think lower
|dw:1523654006600:dw| just have to know this, the magnetic field increases as loop # increases
anyway for b)|dw:1523654038307:dw|
basically an electromagnet is used to induce a magnetic field there's a wire coil placed in the magnetic field; it experiences a torque as the magnetic field because the field exerts a force on either side of the loop in different directions the rotation of the coil is harnessed as mechanical energy
