  1. Move a Charge(Make a Magnet) Music by Kenny Alphin and John Rich Words by me

  2. Well, a current through a wire Makes a compass needle turn And I burn, and I yearn To internalize all there is to learn.

  3. The magnetic lines curl right around When the current’s flowing straight downthe wire: With more spacing as you move away.

  4. Refrain: When electric charges move, ‘cause they’re feeling energetic, They create a brand-new field whose effect is so magnetic. Any charge to cross those lines feels a right-handed force All the boys say:“Move a charge, make a magnet!” Everybody says:“Move a charge, make a magnet!”

  5. When the charge moves around in a circle Or a coil or solenoidThen what it sets up is a dipole field! In a permanent-type magnet, the field begins With electron spins, then some align: They all combine to make a bigger yield.

  6. Refrain: When electric charges move, ‘cause they’re feeling energetic, They create a brand-new field whose effect is so magnetic. Any charge to cross those lines feels a right-handed force All the girls say:“Move a charge, make a magnet!” Everybody says:“Move a charge, make a magnet!”

  7. Where to point qv B. Since that Lorenz force might be a source of confusion in a physics course Use your right hand to understand For closed paths around a magnetic field Induced potential is revealed By the rate of change of flux Inside those hoops.

  8. This leads to applicationsSuch as power generation And that elegant creation, the transformer. Where power in equals power out Stepping voltage up steps the current down The high-voltage side wraps the fieldMore times around. You got that now?

  9. Refrain: When electric charges move, ‘cause they’re feeling energetic, They create a brand-new field whose effect is so magnetic. Any charge to cross those lines feels a right-handed force All the boys say:“Move a charge, make a magnet!” All the girls say:“Move a charge, make a magnet!” What? What?“Move a charge, make a magnet!” Everybody says:“Move a charge, make a magnet!”
