A wire carrying a steady current from east to west is levitated by being placed in a uniform magnetic field. Which direction must the field point? North South Downward, with gravity Upward, against gravity
the magnetic field west of the wire with current into the page is a)East b)west c)north d)south
The size of the magnetic force on a straight wire of length L carrying current I in a uniform magnetic field with strength B is F=ILBsin(?). Here ? is the angle between the direction of the current (along the wire) and the direction of the magnetic field. Hence Bsin(?) refers to the component of the magnetic field that is perpendicular to the wire, B?. Thus this equation can also be written as F=ILB?. The direction of the magnetic force on...
How large a current would a very long, straight wire have to carry so that the magnetic field 1.90 cm from the wire is equal to 1.00 G {comparable to the earth's northward-pointing magnetic field)? I = A If the wire is horizontal with the current running from east to west, at what locations would the magnetic field of the wire point in the same direction as the horizontal component of the earth's magnetic field? at all points directly north...
Question 3 2 pts (a) A 1.00-m long wire carries a 3.00-A current in a region with a magnetic field B = 5.00x10-ST. If the magnetic force on the wire is F = 6.34x10-5N, what is the angle between the wire and the magnetic field? O Answer: (b) If a wire carries a current east and the magnetic field points north, which direction is the magnetic force on the wire? (north, south, east, west, up or down) Answer:
A straight, vertical wire carries a current of 2.20 Adownward in a region between the poles of a large superconducting electromagnet, where the magnetic field has a magnitude of B = 0.564 Tand is horizontal. Part A What is the magnitude of the magnetic force on a 1.00 cmsection of the wire that is in this uniform magnetic field, if the magnetic field direction is east? F= Part B What is the direction of this magnetic force? south west north...
A straight 2.20 m wire carries a typical household current of 1.50 A (in one direction) at a location where the earth's magnetic field is 0.550 gauss from south to north. A.) Find the direction of the force that our planet's magnetic field exerts on this cord if is oriented so that the current in it is running from west to east. Please choose: a. Force is directed upward; b. Force is directed downward; c. There is no force exerting...
A long, straight, north-south wire is carrying a current northward of 15 A. a) What is the magnitude and direction of the magnetic field at a location 0.4 m directly to the east of this wire? b) If a proton at the location in Part A was traveling away from the wire at a velocity of 8,000 km/s, calculate the magnitude and justify the direction of the magnetic force on this proton?
