Self-inductance of a small circular loop. consider a single loop of radius a, with a counter-clockwise current i, as shown in the figure to the right. assume that the loop wire is infinitely thin and the radius a is very small. the effect of assuming a small loop radius is that one can take the magnetic field inside the loop to be approximately constant and equal to the magnetic field at the center of the loop. i. recall from lecture 15 (see slide #16), that the magnetic field at the center of the loop is hel and is pointed out of the page. using the assumption that the loop has a small enough radius to treat the magnetic field inside the loop as constant and equal to the value at the center, calculate the magnitude of the magnetic flux through the loop. dl(t) we change the magnetic field due to this in turn induces an emf. if everything else in the problem other than the current remains unchanged, calculate the magnitude of the induced emf in the loop. is the induced emf directly or inversely proportional to a[hint: use faraday's law.] dl(t) di(t) 3. in the relationship between the induced emf in the loop and" the proportionality constant is called the self-inductance of the loop. using your result from question 2, what is the self- inductance of the loop shown in the figure?

Apatient has a history of poor nutrition. he has skin rashes, bleeding gums, and a cut that hasn’t healed in a long time. what vitamin deficiency most likely caused this symptom?

Fill in the blanks with the numbers is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
