If you drop a bar magnet down a tube made of conducting material (like copper or...
Will dropping a bar magnet down a long copper tube produce a current in the tube? Explain.
A rectangular coil lies flat on a horizontal surface. A bar magnet is held above the center of the coil with its north pole pointing down. What is the direction of the induced current in the coil? A) counterclockwise B) clockwise C) No current in the coil D) None of previous is correct BTW: I know the answer, just please explain (include formulas if needed)
Physics question.
Suppose that a bar magnet falls through a conducting hoop of wire with its north pole facting downward. Three consecutive snapshots of its descent are shown below. For each snapshot, state whether: the magnetic flux through the loop is upward, downward, or zero; the induced current is clockwise, counterclockwise, or zero, from the point of view of an observer looking down from above the loop. Make a qualitative sketch of the induced current versus time (taking counterclockwise as...
You have a piece of copper (conductivity = 6.0*10^7 Ω^-1m^-1) wire 26 cm long and 2.0 mm in diameter and a bar magnet with a magnetic dipole moment of 0.75 Am^2. You decide you’re going to make use of induction to make some current flow in the wire. First, you pull the copper wire into a circular loop. Then you hold the bar magnet 15 cm above the center of the loop, parallel to the loop so that there is...
answer all Q pls
8. A bar magnet is dropped through a loop of copper wire as shown. Recall that ou magnet, magnetic field lines point away from a north pole and toward a south p positive direction of the induced current I in the loop is as shown by the arrows on the loop, the variation of I with time as the bar magnet falls through th by which of the following graphs (the time when the midpoint of...
b) How does the magnitude of the induced current depend on the strength of the bar magnet? PHY290 c) If the secondary solenoid is in a circuit with resistance R, there will be an induced current, 12 = Discuss how the equations predict the direction of the current in the secondary coil depending on whether the current in the primary coil, 71, is increasing or decreasing. Is it increasing or d) Does this match your decreasing?) s this match your...
ADVANCE STUDY ASSIGNMENT: COULOMB'S LAW PURPOSE of tl of this exercise is to become familiar with the force between electric point charges which is descrbed by Coulomb's law. In particular, we will investigate the force's inverse-square dependence on separation distance between charges. DISCUSSION A basic characteristic of electric charge is that charges exert forces on each other, like charges positive-positive and negative-negative) repel each other while opposite charges (positive- and constitute a Newton's third-law pair; that is, they are equal...
Analysis of Pricing: You manage The Atlantic Taffy Company which makes a saltwater taffy bar for sale to gift shops from Atlantic City, New Jersey, to Mount Desert Island near Bar Harbor Maine. The company sells individually wrapped bars in boxes of 50 for $81.00 each. The candies retail for $3.99 for an individual bar and sales have been strong. The owners of the Atlantic would like to increase its sales and profits. They know that, if price is lowered,...
Imagine that you are in class and have a sudden urge to gulp down a hot fudge sundae. Some part of you really wants to just grab a giant sundae and start eating it right this second. But then, another part of you realizes that a giant hot fudge sundae has lots and lots of calories in it, and makes you feel weak and even guilty for even considering eating something like this. Ultimately, you decide to wait until class...
please help with a detailed, fully explained answer
for Question 2. thank you
