Explain what causes an electron to move toward one end of a wire when the wire is moved across a magnetic field. (Select all that apply.) The interaction between the charge of the electron and the magnetic field creates a force on the electron, causing it to move.
A moving electron creates its own electric field.
A moving electron creates its own magnetic field.
The magnetic field induces a region of positive charge which attracts the electron toward one end of the wire.
The interaction between the electric field of the electron and the magnetic field creates a force on the electron, causing it to move.
An electron has its own magnetic field.
None of these are true.
The interaction between the magnetic fields creates a force on the electron, causing it to move.

Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. so it is no surprise that such clothing has largely replaced thickand heavy old-fashioned coats. (a) consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 w/m·°c) with 1.5-mm-thick air space (k = 0.026 w/m·°c) between the layers. assuming the inner surface temperature of the jacket to be 28°c and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0°c and the heat transfer coefficient at the outer surface is 25 w/m2·°c. (b) what would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? what should be the thickness of a wool fabric (k = 0.035 w/m·°c) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a five-layer ski jacket?
