a) Compare and contrast magnetic and electric fields. Your answer should include at least 2 ways they are similar and 2 ways that they differ. b) Include a diagram of an electric field for a positive test charge and a diagram for a typical bar magnet. Make sure you show the field lines (including direction) and label the charges and poles.

You have learned that a charge moving in an magnetic field can experience a magnetic force. Remarkably, anytime that a charged particle moves that particle produces its own magnetic field! The image below of magnetic compasses forming a circle around a current-carrying wire demonstrates the shape of the magnetic field. The magnetic field lines forms concentric circles around that wire. The strength of the field decreases with increasing distance away from the wire. DOCES PAMIE DOCERE B If the current in the wire is 7.79A, what is the magnitude of the magnitude of the magnetic field (in μT, or micro-Tesla) a distance of 0.32m away from the wire? Note: It is understood that the unit of your answer is in μT, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.

A wire having a mass per unit length of 0.002 g/m carries an unknown current horizontally to the right. The wire is in a magnetic field of 0.10 T pointing into the page. a.   Create a drawing and a free body diagram for this situation What current in the wire is needed in order for the wire to be in magnetic levitation?
