A wire is placed on a table from West to East and has a current running through it from West to East. What direction is the magnetic field to the North of the wire? Select one: a. Into the table b. There is no magnetic field present c. Out of the table d. Pointed towards the East e. We cannot tell f. Pointed towards the South g. Pointed towards the North h. Pointed towards the West

If a magnetic field of no more than 1.0 x 10-3 T is to be allowed 30 cm from an electrical wire, what is the maximum current the wire can carry? PLEASE WRITE CLEARLY SO I CAN UNDERSTAND THE FORMULAS.

From where highways404 (running north and south)and the 401(running east and west) cross in Toronto, car A is 100km north of the 401 travelling south (towards the 401) at the constant speed of 100km/hour. Car B is 200km west of the 404 travelling east (towards the 404) at a constant speed of 100km/ hour. Assuming both cars do not stop, find the time that the cars are at theirminimum distance from each other.? What is that distance?

Imagine that you have placed a compass due east of of a wire where current equals 2A (the wire is vertical and current travels from bottom to top). 1. If you turn the current on, how would the compass respond? (Does it change cardinal direction?) 2. How does the magnitude and direction of the total magnetic field change? PLEASE EXPLAIN!

A long, straight wire carrying a current I1 is placed on a horizontal table in front of you and the direction of the current points +x axis. The magnetic field produced by the current I1 at a point 5 cm above the wire is 0.2 T. A second parallel wire carrying a current I2 = 3I1 is placed 10 cm above the first wire and the direction of the current also points +x axis. What is the magnitude of the...

A 2.00-m length of wire is held in an east–west direction and moves horizontally to the north with a speed of 0.500 m/s. The Earth’s magnetic field in this region is of magnitude 50.0 mT and is directed northward and 53.08 below the horizontal. (a) Calculate the magnitude of the induced emf between the ends of the wire and (b) determine which end is positive.

Johnny C. has two divisions. East division sells a component (L689) to West division. West then assembles a product, CAGE, using L689 and sells it to customers. East division incurs $50 of variable cost per unit of L689 and allocates $80 of fixed cost to each unit. East’s factory has limited space, so every unit of L689 it produces means one less unit of L690 is made. While L689 is only sold to West division, East division sells L690 to...
