how does adding an iron bar to a solenoid affect the magnetic field of the electromagnet?\no it changes the magnetic field to a current.\no it changes the magnetic fields direction.\no it increases the magnetic fields strength.\no it decreases the magnetic fields strength.

how does adding an iron bar to a solenoid affect the magnetic field of the electromagnet?\no it changes the magnetic field to a current.\no it changes the magnetic fields direction.\no it increases the magnetic fields strength.\no it decreases the magnetic fields strength.

Answer

Brief Explanations:

Iron is a ferromagnetic material. When an iron bar is added to a solenoid, the iron atoms align with the magnetic field of the solenoid. This alignment of magnetic - domains in iron enhances the overall magnetic field, increasing its strength.

Answer:

It increases the magnetic field's strength.
