6.10 Sketch and recognise magnetic field patterns for a straight wire, a flat circular coil and a solenoid when each is carrying a current

Straight wire
Basically little circles around the wire. Direction determined with right hand grip. (fig 1)

Figure 1

Solenoid (coil of wire)

Sort of like a regular magnetic field...in a tube... (fig 2) Direction can be found with right hand grip.

Figure 2

Flat coil

Like a regular wire x2 with a line in the middle. Again, determined with right hand grip. (fig 3)
