Magnetic poles always come in pairs (North and South); you can't have just one. A changing magnetic field creates an electric field.
This is the "magic" behind power plants. If you spin a coil of wire inside a magnetic field, the magnets push the electrons in the wire, creating electricity. This is how we generate almost all the power we use today. 3. Maxwell’s Equations (The "Scary" Part Made Easy) Electromagnetism For Dummies Pdf
A changing electric field (or a current) creates a magnetic field. 4. Why Does It Matter? Magnetic poles always come in pairs (North and
