A student is asked to build and demonstrate a working temporary magnet called an electromagnet. The student is very confused on which items to use to create a temporary magnet. Choose the best items the students should use to create the electromagnet. iron nail with warn iron nail with copper wire plastic spoon with yarn plastic spoon with copper wire

36. *There is a uniform magnetic field of magnitude 2.2 T in the +z direction. Find the force on a particle of charge -1.2 nC if its velocity is (a) 1.0 km/s in the y-z plane in a direction that makes an angle of 40° with the z axis and (b) 1.0 km/s in the x-v plane in a direction that makes an angle of 40° with the x axis.

A charged particle is moving through a big field and experiences of magnet force Fb>0 The big field vector is shown, determine all that could represent the velocity

An iron nail can be turned into a magnet if it is held in a strong magnetic field. The type of magnet that the nail becomes in this situation is a(n): O temporary magnet electromagnet O field magnet conventional magnet O polar magnet

Which of the above objects falls in each category?  The bar magnet  The magnetic car  The nail  The copper and zinc electrodes (the spade-shaped pieces of metal).  Category 1 objects will not or attract or repel anything magnetically. Category 2 objects will be attracted to category 3 objects.  Category 3 objects will be attracted to category 2 objects, and will either attract or repel other category 3 objects, depending on how they are oriented.

Select all of the following descriptions that match what happens when a ferromagnetic material is placed in an external magnetic field.   1) The ferromagnetic material becomes negatively charged. 2) Nothing, ferromagnetic materials do not interact with magnetic fields. 3)The ferromagnetic material rapidly cools. 4)The ferromagnetic material becomes positively charged. 5)The external magnetic field induces magnetic poles in the ferromagnetic material. 6)The ferromagnetic material becomes magnetized.
