Question

how does adding an iron bar to a solenoid affect the magnetic field of the electromagnet? it changes the magnetic field to a current. it changes the magnetic field’s direction. it increases the magnetic field’s strength. it decreases the magnetic field’s strength.

Answer 1

Adding an iron bar to a solenoid increases the magnetic field's strength. The iron bar becomes magnetized by the magnetic field produced by the solenoid, which in turn strengthens the magnetic field.
