Refrain:

In my mind I've got physics equations,

Faraday and Ampère tell you how to be where.

Governing the world we live in: this is why I care, and have

Physics equations in my mind.

Verses:

Force that's due to electric field

Is *kqq* over *r* squared,

Which also equals *q* times *E*.

And Voltage equals *U* over the

Test charge; Now I've

Got physics equations in my mind.

Now *V*'s the minus integral

Of **E** dot d**l** from *A* to *B*,

And **E** equals minus **del** *V*.

But voltage superposes and is *kq* over *r*;

I've got physics equations in my mind.

(refrain)

Verse:

**E** dot **n-hat** times d*A* is

What we call electric flux.

*Q* over epsilon-naught as well.

But for flux due to a magnet just use **B** instead

I've got physics equations in my mind.

Bridge:

And the EMF is just the time derivative

Of magnetic flux times minus one.

And the magnetic force is *q***v** crossed with **B** .
. .

But no monopoles . . .

So I've got physics equations in my mind!
