A magnetic field is made by electric currents that is induced from opposite terminals of charges. When a current-carrying conductor is placed in a magnetic field, the electrons move to a certain direction. The guide used for this is Fleming's Left-Hand Rule as shown in the picture. It shows that the motion of the electron is in right angles or perpendicular to the force of the magnetic field. The resulting path of the direction of the electron will be in circular motion.This is the concept used in transformers where a voltage is induced from coils of currents. The electrons move in a helical or circular motion.

How do you know when electric current is flowing in a lightbulb circuit?
daser333 [38]
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.

Rufina [12.5K]

The magnetic field along the central axis of the cylinder will be <em>determined </em>using the formula given that all parameters are known

dBz=\frac{uoR^2di}{2r^3}

<h3>Magnetic field </h3>

Generally, A magnetic field is also referred to as a vector field that shows the magnetic presence on electric charges and magnetic materials.

The formula for magnetic field  is

Where

u=4\pi*10^{-7H/M}

Therefore, the magnetic field along the central axis of the cylinder will be determined using the formula given that all parameters are known

A student wishes to work out how much power she uses to lift her body when climbing a
Bess [88]

Answer

i'm not 100% sure but 1764

Explanation:

Work done = gravitational potential energy

Gravitational potential energy = mass(kg) × height(m) × gravitational field strength(N/kg)

We can assume that the student is on earth so the gravitational field strength is 9.8N/kg

So work done = 60 × 3×9.8

=1764

(if you need help calculating power but if you do just divide your answer by 12 and you will get 147)

. a boat can travel in still water. (a) if the boat points directly across a stream whose current is what is the velocity (magni
mixer [17]

a) The velocity of the boat relative to the shore is 3.40 m/s and b) The position of the boat relative to its point of origin after 3s is 10.20m.

Here it is given that the speed of the boat (x) = 2.20m/s

The speed of the stream current (y) = 1.20m/s

a) We have to find the velocity of the boat relative to the shore.

The speed of the boat = x + y

                                    = 2.20 + 1.20

                                    = 3.40m/s

b) Now we have to find the position of the boat after 3s

The formula for speed:

Speed = Distance/ Time

distance = speed × time

speed = 3.40m/s

Time = 3s

distance = 3.40 × 3

              = 10.20 m

Therefore we get a) speed as 3.40m/s and b) distance as 10.20m.
