What is the difference between magnetic and electric fields?

What exactly is the difference between magnetic and electric fields? I’ve got the impression it’s basically the same thing accept electric fields are produced only by electricity and magnetic fields are produced by magnets
(and electricity?). Could someone just explain it simply, preferably without using too complicated sciency words! Thanks.

They are closely related, and even transform into each other under changes of reference frame. But there are some important differences.

Assuming static fields (ones that don't depend on time), electric fields are sourced by **charges**, while magnetic fields are sourced by **currents**. (If you allow time-varying fields, then time-varying electric and magnetic fields are also sources for each other.)

Another difference is in how particles respond to the fields. Electric fields exert forces on any charge, while magnetic fields only exert forces on *moving* charges.
