Describe light according to the current accepted theory, be very detailed

Light is made up of individual packets. Each packet is made up of two perpendicular transverse waves: one that consists of an oscillating electrical field, and one that is made up of an oscillating magnetic field.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
