Questions & Step-by-Step Solutions
What is the effect of increasing the current in a coil on the magnetic field strength?
Correct Answer: Magnetic field strength increases.
Step 1: Understand what a coil is. A coil is a wire wound in a spiral shape.
Step 2: Know what current is. Current is the flow of electric charge through the wire.
Step 3: Learn about magnetic fields. A magnetic field is an area around a magnet where magnetic forces can be felt.
Step 4: Realize that when current flows through a coil, it creates a magnetic field around it.
Step 5: Understand the relationship between current and magnetic field strength. The more current that flows through the coil, the stronger the magnetic field becomes.
Step 6: Conclude that increasing the current in the coil will increase the strength of the magnetic field.
