Question

Maya sets up two experiments as shown. What question is Maya most likely trying to answer? How does the type of material used in the core affect the strength of an electromagnet? How does the number of loops of wire affect the strength of an electromagnet? How does the speed at which an iron bar is removed from wire loops affect the strength of an electromagnet? How does the thickness of the wire affect the strength of an electromagnet?

Answer 1

D

Step-by-step explanation:

The correct answer is D

How does the thickness of the wire affect the strength of an electromagnet?

Answer 2

How does the thickness of the wire affect the strength of an electromagnet

Step-by-step explanation:

Generally, electromagnet strength increases with an increase in wire thickness. From the theory of electric circuit, the resistance of an electric wire is inversely proportional to the cross sectional area of the electric wire. Mathematically, we have:

R ∝ 1/A

Where:

R is the resistance of the electric wire; A is the cross sectional area of the wire. Therefore, for a large cross sectional area, the resistance will be very low, and the electric current passing through the electromagnet will be high. This will create a very high magnetic field. Thus, the question that Maya will most likely answer is: How does the thickness of the wire affect the strength of an electromagnet.
