A 10-turn ideal solenoid has an inductance of 4. 0 mh. to generate an emf of 2. 0 v the current should change at a rate of:_____
Lady bird [3.3K]

The answer is 500 A/sec.

N=10 ; Solensid; L=4 m H ; \varepsilon=2 \mathrm{~V};

\begin{aligned}&\varepsilon=-L \frac{d I}{d t}=N \phi ; \\&2 \times \frac{1}{L}=-\frac{d I}{d t} ; \\&2 \times \frac{1}{4 \times 10^{-3}}=-\frac{d I}{d t} ;\end{aligned}

0.5 \times 10^{3}=\frac{d I}{dt}

So, 500 A/sec.

What is Solensid?

  • Electromagnets are magnets in which the wire is coiled around an iron core. When an electric current is applied to the iron core, a magnetic field is formed around it. When the power is turned off, the magnetic field dissipates. The wire-wound core of the magnet is ferromagnetic or ferrimagnetic in nature. The most prevalent material utilised in the core is iron.
  • The magnetic field created is governed by the availability of power. A permanent magnet does not require electricity, and its magnetic field cannot be changed. Solenoid, MRI machines, hard drives, relays, motors, loudspeakers, and generators all employ electromagnets.

According to the Doppler Effect, which statement is true about a sound as it approaches you and then moves away.
Fiesta28 [93]
As the source approaches you, the sound waves are compressed, so
the pitch of the sound is higher than what the source is actually emitting.

Then, after it passes you and begins moving away, the sound waves
are stretched, so the pitch of the sound is lower than what the source
is actually emitting.
