Try moving the magnet in the different ways described in the table below,. Record your observations in the second column of the

table. MotionMove the magnet straight through the coil, leading with the north pole. Once the magnet is completely through, move it back to its original position. Move the magnet straight through the coil, only this time leading with the south pole. Once the magnet is completely through, move it back to its original positionPut the magnet in the center of the coil, but don't move it. Put the magnet on the outside of the coil. Repeatedly move it up and down while outside of the coil. Keeping the magnet outside of the coil. Repeatedly move it back and forth horizontally.Place the magnet back inside of the coil. Now repeatedly switch the polarity of the magnet by pressing the button toward the bottom-right of the page over and over again.

Base on the experiment, we can deduce that the working principle of most electric generators is based on spinning a permanent magnet near coils of wounded wire.

<h3>What is Faraday's law of electromagnetism?</h3>

Faraday's law of electromagnetism states that the negative rate of change of time (Δt) of the flux of the magnetic field (∅) through a surface is directly proportional to the flux (∅) of the electric field through a surface that has the loop as its boundary.

Electric generators are primarily designed and developed to use the properties of electromagnetism to convert kinetic energy (KE) that is possessed due to motion, into electrical energy. Thus, we can deduce that the mode of operation or working principle of most electric generators is based on spinning a permanent magnet near coils of wounded wire.

Above the ground, a 1 m long wire is suspended horizontally perpendicular to a line running from its center to a nearby observer
Anit [1.1K]

Answer:

a) 0.09N b) positive x direction

Explanation:

Force on a conductor carrying current in a magnetic field can be expressed as;

F = BILsin(theta) where

F is the force on the conductor (wire)

B is the uniform magnetic field I'm Tesla = 1.8Tesla

I is the current in the wire = 5×10^-2A

L is the length of the wire = 1m

theta is the angle that the conductor make with the magnetic field = 90° (since the wire in the horizontal direction is perpendicular to the field acting upwards)

Substituting this value in the formula to get F we have;

F = 1.8×5×10^-2×1 × sin90°

F = 0.09N

The force on the wire is 0.09N

b) The direction of the force is in the positive x direction since the wire acts horizontally to the magnetic field.

Inessa [10]

Answer:

90m

Explanation:

Distance is not a vector but a scalar quantity. depicted by a quantity only.

hence:

Distance is equal to 30+40+20 = 90 m
