An electromagnet produces a magnetic field of 0.500 T in a cylindrical region of radius 2.0 cm between its poles. A straight wire carrying a current of 10.0 A passes through the center of this region and is perpendicular to both the axis of the cylindrical region and the magnetic field. What magnitude of force does this field exert on the wire

Force = 0.1N

Explanation:

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. ... The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

Magnitude of the force is given by ILB SIN90 = ILB

where I is current.

L = lenth

B= magnetic component (Tesla)

Force = 10 * 2/100 * 0.5

Force = 0.1N.

which three statements are true about all alloys?

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
