which of the following electromagnets would have the greatest magnetic field? (1 point)
which of the following electromagnets would have the greatest magnetic field? (1 point)
Answer
Explanation:
Step1: Recall magnetic - field factors
The strength of an electromagnet's magnetic field depends on the number of turns of wire and the current flowing through it. For a simple electromagnet setup with a battery, more turns of wire around the core will result in a stronger magnetic field (assuming the same battery voltage, so the current remains relatively comparable in simple cases).
Step2: Analyze the options
Looking at the diagrams, the electromagnet with the most number of wire turns around the core will have the greatest magnetic field.
Answer:
The electromagnet with the most number of wire turns around the core (the last option in the sequence of diagrams as it has the most coils).
