the ans is ther are no structures in electromagnet
Magnetic resonance imaging, or MRI, is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. Sometimes a contrast solution is injected into the patient during the MRI scan to show certain structures more clearly.
MRI
It depends on the computer, but quite possibly. The probes sent to investigate Jupiter were specially constructed to minimize possible damage caused by radiation or magnetic fields.
The Magnetic Fields was created in 1989.
Magnetic fields can be blocked. Magnetic fields cannot penetrate a superconductor, and regions can be shielded from magnetic fields using ferromagnetic materials.
magnetic fields are essential to production of electricity
Paper is not affected by magnetic fields.
