Ryan is experimenting with core materials for an electromagnet. He slides different core materials through a coil of current-carrying wire. Sort the core materials based on whether they will or won’t increase the strength of Ryan’s electromagnet.woodsteelsilvernickelironglass

The figure shows a simple electromagnet made of a coil of insulated wire wrapped around an iron nail.When the switch closed, which of the following will make this electromagnet stronger? (i) increasing the number of coils(ii) adding more turns to the coil(iii) increasing the direct current flowing through the coil(iv) changing the direct current flowing through the coil to alternating current.*1 pointii, iiii, ii, iiiii onlyiii only

The coils of wire surrounding the iron core of an electromagnet are called:a split ring commutator.1an armature.2a solenoid.3a brush.
