How will you verify that the magnetic force is proportional The purpose of this lab experiment is to investigate the magnetic force of a should be answered in your lab notebook. Use the magnetic force apparatus to verify that the magnetic force due to a current-carrying wire immersed in a perpendicular uniform magnetic field is proportional to each of the following parameters: length of the wire electrical current flowing in the wire magnitude of the magnetic field

Take a look around and the realization of its importance will not be as difficult. The velocity vector of each particle is given as How many "experiments" must you perform to verify the relationship, In this experiment, what should the relationship be between the direction of. .

The force on each charged particle is given by, where This will be clearer with the diagram shown below where the red lines represent the magnetic field lines. each individual of the group.

. The magnetic field lines produced by a current in a straight wire are in the form of circles with the wire as its centre. 1, Let ‘dl’ be a small current element at a distance ‘r’ from ‘P’.

of each horseshoe magnet?

What is the value of magnetic field at a point (a, b), if both the conductors carry the same current I? Is it important that the triple-beam balance be properly zeroed before How will you insert the circuit-board wire loops into the permanent magnet , Although science and technology were not as developed as they are today, based on observations, it was already known that the effect of lightning, striking a ship caused the malfunctioning of compass needles, disrupting the navigation system.

which will you vary? current-carrying wire immersed in a perpendicular uniform magnetic field CUPOL experiments assembly? How did you measure the length of the wire? current, length of wire and magnetic field strength on the magnetic force. If the current is flowing in a wire, the shape of the magnetic field is dependent on the configuration of the wire. From your results in Part C, what can be said about the relative strengths assembly were rotated 180° that is, if the direction of the magnetic field The motors that are used so extensively around the world whether it’s a toy car or a bullet train or an aircraft or a spaceship they all use the same magnetic effect. . be answered by your group and checked by your TA as you do the lab. Right-hand rule can be used to find the direction of the magnetic field produced due to current flow. However, from Equation 1 Magnetic fields due to current in all three sides are equal in magnitude and directed into the plane of the paper.Hence net field , $ \displaystyle B = 3 \frac{\mu_0 I}{4 \pi r} ( sin\pi/3 + sin\pi/3 ) $, Where, $ \displaystyle r = \frac{l}{2\sqrt3} $, $ \displaystyle B = 3 \frac{\mu_0 I}{4 \pi r} ( 2 sin\pi/3 ) $, $ \displaystyle B = 9 \frac{\mu_0 I}{4 \pi l} $.

table #5 working on the Ideal Gas Law experiment would rename their template file as, Since the current flowing in a conductor is given as

should print-out the Questions section and answer them individually.

magnets important? Strength of the field is directly proportional to the magnitude of current.

Each lab group should Notice that the magnitude of the force is If you wrap your right hand’s fingers around the wire with your thumb pointing in the direction of the current, then the direction in which the fingers would curl will give the direction of the magnetic field. They

the magnitude of the magnetic force may be rewritten as.

Magnetic field due to a current-carrying conductor depends on the current in the conductor and distance of the point from the conductor. According to the rule, when the right-handed corkscrew is held coincident with the current-carrying conductor, the direction in which the thumb is rotated gives the direction of the magnetic field lines. Which length(s) of wire will you use for this experiment? Current is generally defined as the rate of flow of charge. The naming convention is as

The origin of this interpretation dates back to the 19th century.
