Question

1. the strength of an electromagnet is directly proportional to the number of turns of wire around the core material and the amperes flowing within the conductor. this is referred to as ampere-turns.

true

false

Explanation:

Define the relationship in electromagnetism

Using the Electromagnetism knowledge point
The magnetic field strength \(H\) inside a solenoid or electromagnet is directly proportional to the magnetomotive force (MMF), which is defined as the product of the number of turns of wire \(N\) and the electric current \(I\) in amperes flowing through the conductor:

$$ \text{MMF} = N \times I $$

This product is measured in units called ampere-turns.

Evaluate the statement

The statement asserts that the strength of an electromagnet is directly proportional to both the number of turns of wire and the amperes flowing within the conductor, and that this product is referred to as ampere-turns. This is physically accurate because increasing either the current or the number of turns increases the magnetic field strength proportionally.

Answer:

• True (Correct answer)
• False
