Question

Can someone help with#1,3 &4 magnetic force on a wire lab. Compare the magnetic force equation and the general equation for a straight line to prove each graph you made should be a straight line. Use this to show what the slope and y-intercept of each graph should be in terms of I, L and B. Using the slope that you found for each graph, determine the strength of the magnetic field due to these magnets. You should be doing this twice. Explain why the magnet on the balance moved when current was sent through the wire. Explain clearly the physics that is happening here. If a horizontal wire of length, L and mass, M is carrying a current, I to the west and it is floating stationary above the surface of the earth, what must the magnitude and direction of a magnetic field have in order to cause this? Show how you are arriving at your answer See: http: /hyperphysics.phy-astr.gsu.edu/hbase/magnetic/forwir.html

Explanation / Answer

(3). The wire acts as a conductor and when current flows through the wire and magnet is placed on the balance,

the conductor experiences a magnetic force.

The experiment known as Oersted's Experiment established that a current carrying wire exerts a force on the magnet. The magnet also exerts equal and opposite force on the current carrying wire.

Due to the magnetic force experienced, The magnet on the balance shows movement.

(4). Let us consider that the magnetic field B is exerting a force F on the wire.

The length of the wire = L

The force F is calculated by a vectorial product and it must counterbalance the weight of the wire

The weight of the wire = Mg i.e W= Mg

then the force F is directed vertically and in a direction opposite to the direction of W.

F = -W

The force is calculated by the formula,

F= ILB

Where, I= Current flowing through the wire

L= length of the wire

B= Magnetic field

since F = ILB,

F= -W= - Mg(consider only the magnitude, minus sign represents the direction wghich is oppoosite to F)

=> ILB = Mg

=>B= Mg/IL
