Question

Create a formula giving the strength of the induced field (B) in terms of current (I) and the distance from the wire to the probe (d).

Answer 1

@rajathsbhat can u help please?

Answer 2

do you have a picture?

Answer 3

noo it's just a sentence telling me to create a formula

Answer 4

it's magnetic induction

Answer 5

you have something i don't.....are you sure this is all the data you've been given?

Answer 6

hold on

Answer 7

this was the question before this one

Answer 8

6. Analyze: To determine the strength of the induced field, subtract the strength of Earth's magnetic field from the total strength of the field. What do you notice about the relationship between the distance from the wire and the strength of the induced field?

Answer 9

and then after that question came this one

Answer 10

Now, divide the current (20 amps) by the distance the probe is from the wire (d). (Note: The distance from the wire is given by the x-coordinate of the probe's position.) Use this value to complete the fourth column of the table.

What do you notice about this value

Answer 11

after that question came the original one where to create a formula

Answer 12

I mean, what object are we talking about here? that's my question...the wire, the probe...wht are they referring to?

Answer 13

So it says to create a formula depicting the strength of the induced firl (b) and the distance (d) so lets say if the strength goes down the distance must be small and if the strength of the induced field is high the distance must be big?

Answer 14

looks like here is a nice article on it.
