Magnetic field strength decreases as you get farther from the poles. Does the flux through the face of the coil change as you move the magnet? Explain your reasoning.

Why does the needle of the Galvanometer deflect when you bring a magnet in close to the coil? Is the deflection in accordance with Lenz's Law? Justify your answer in terms of Lenz's Law and your answer above.

Explain the steps to obtaining an electric field, magnetic field, electric flux, and magnetic flux.

The magnetic flux through a 10.0-cm2cm2 loop is 8.0 T⋅cm2T⋅cm2, and the magnetic field at the...

The magnetic flux through a 10.0-cm2cm2 loop is 8.0 T⋅cm2T⋅cm2, and the magnetic field at the location of the loop is uniform. Choose all correct answers. Check all that apply. A)If BB = 1.0 TT, then the angle between the B⃗ B→ field and the normal to the loop's surface is greater than 0∘∘. B)If the direction of B⃗ B→ field is parallel to the normal to the loop's surface, then BB = 0.8 T. C)The magnitude of the B⃗...

a) How does the magnetic flux through the loop changes as the magnet rotates. Is the flux maximal when the magnet is horizontal or vertical on the screen? Why? b) How does changing the magnetic flux works to create an emf (potential difference) in the coil, which alternates over time (use the Faraday’s law equation)?

How do magnetic flux and magnetic fields relate to magnetic field lines?

1 a) What is the approximate electric field strength and magnetic field strength of the electromagnetic waves radiated by a 60-W lightbulb, as measured 5.5 m from the bulb? You can assume that the bulb is 100% efficient in converting electrical energy to light energy. b.) Incandescent light bulbs are very inefficient. Find the electric field strength and magnetic field strength assuming 5% efficiency. Please show all work, thank you!

A charge is passing through a static magnetic field. The speed of the charge does not change as it passes through the field

A charge is passing through a static magnetic field. The speed of the charge does not change as it passes through the field. True of False?

You are designing magnetic motors. A colleague1 insists that like magnetic poles attract— north poles attract north poles and south poles attract south poles. You feel the need to remove this idea from his head. You possess three unlabeled bar magnets (that is, you don’t know which ends are N or S). Surely that will be enough. . . [Bonus points for writing this as a dialogue. Extra bonus points for writing this in iambic pentameter.]

An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanner's 1.60 T field with his fingers pointing in the direction of the field. His wedding ring has a diameter of 2.15 cm, and it takes 0.380 s to move it into the field. (a) What average current is induced in the ring if its resistance is 0.0100 Ω? (Enter the magnitude in amperes.) _________A (b) What average power is dissipated (in...

When a DC current passes through the coil, it will produce a magnetic flux around the coil. Is this the reason why the coil get heated? Because the magnetic flux will be stable after all as DC current does not oscillate?
