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...
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?
2. A very long, straight wire runs from west to east. The wire is 17 m long and carries a 2.6 A current that moves from west to east. a. Earth's magnetic field is approximately uniform, and is directed from south to north. At the location of the wire, the magnetic field has the strength 4.4 x 10-5 T. Calculate the magnitude and direction of the force that Earth's magnetic field applies to the wire. b. What is the magnitude...
