What role does voltage play in the formation or use of an electromagnet? if you were able to keep the electromagnet that you created in your laboratory activity, what would be two possible uses for the electromagnet? what is an advantage of using an electromagnet rather than a regular magnet?

If you were able to keep the electromagnet that you created in your laboratory activity, what would be two possible uses for the electromagnet?

Electric bells or buzzers

To separate iron and iron objects from a mixture

Explanation:

When a current is passed through current carrying coil with magnetic material at the center, magnetic field is produced. Thus, it acts as temporary magnet. It can be demagnetized by stopping the current. The strength of the magnetic field can be increased by increasing the number of loops and amount of current.

At home, the electromagnet can be used as a buzzer or electric bell. The electromagnet can be connected to a iron armature with a clapper. In the presence of magnetic field, the clapper strikes the bell as the iron armature is pulled towards the field.

The electromagnet can also be used to separate iron objects from a mixture, such as iron nails, clips, pins, needles etc.

the sphincter muscles at the end of the digestive tract is the anus.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
