3. The magnetic field between the coils is given by: B = 520µ0 I (1/x1 + 1/x2) where xi =Ri [4 + (d/Ri) 2 ] 3/2 with Ri their radius and d their separation. a) From the above result the magnetic field between the coils can be written as B = kI for some constant k that depends on the geometry of the coils. Using your values for R1, R2, and d, calculate k. Attempt to estimate the uncertainty on k. k = b) If you were able to determine a non-zero coil current to offset the earth’s magnetic field in part 2, use the above result to determine the component of the room magnetic field BE along the coil axis. How does your estimate for BE compare with the horizontal Earth field component in Santa Monica BE ≈ 0.245 gauss?

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

yup its correct its: c) b b

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
