1

Suppose that a magnetic field is oriented such that it is pointing directly to the left, as in the picture shown below. If a positively charged particle were to begin traveling through this magnetic field to the right, in which direction would the particle's trajectory begin to curve?

Magnetic field

2

A single string of wire has a resistance of $10\Omega$ . If the wire is connected to a power source, what is the strength of the magnetic field away from the wire?

$\mu_o=4\pi \times 10^{-7}\frac{T\cdot m}{A}$
