Question

rank the strength of the magnetic field produced by each of these arrangements from weakest to strongest. wire with no electric current straight wire with electric current coiled wire with electric current around an iron core coiled wire with electric current electric force and magnetic force have many common characteristics. engineers use both electricity and magnetism when they design generators. you will learn more about generators in an upcoming lesson. continue on to show what you learned today.

Explanation:

Step1: Understand magnetic - field generation

A wire with no electric current produces no magnetic field from electric - current effects, so it has the weakest magnetic field.

Step2: Analyze straight - wire current

A straight wire with electric current produces a magnetic field, but the field lines are spread out, so it has a relatively weak field compared to coiled wires.

Step3: Consider coiled - wire without core

A coiled wire with electric current concentrates the magnetic field lines more than a straight wire, resulting in a stronger magnetic field.

Step4: Evaluate coiled - wire with iron core

An iron core in a coiled wire with electric current enhances the magnetic field due to the ferromagnetic properties of iron, making it the strongest.

Answer:

wire with no electric current, straight wire with electric current, coiled wire with electric current, coiled wire with electric current around an iron core
