Question
can you please answer questions #1-21 please. all true or false. thank you very much will give thumbs up !
) A solenoid can be used to produce a reasonably uniform magnetic field. It is a long wire rounded in the form of a helix. An ideal solenoid has very closely packed turns of wires and a length much longer than the radius of the turns. use the right hand rule as the following: when the four fingers are bending along the direction of current flow of the solenoid, use the right hand rule as the following: when the four fingers are bending along the direction of current hlow of the solenoid An ideal solenoid has very closely packed turns of wires and a length much shorter than the radius of the turns. )When the turns on the solenoids are closely packed, the solenoid can be considered as many circular loops. We can the thumb represents the direction of the B field outside the solenoid ) When the turns on the solenoids are closely packed, the solenoid can be considered as many circular loops. We c the thumb Tepresents the direction of the B field inside the solenoid. ) For an ideal solenoid, the B field is uniform inside it and is close to zero outside it. ) For an ideal solenoid, the B field is uniform outside it and is close The cross section of a solenoid is shown her e tTbe amount of current enclosed by the dashed loop is 101. The amount of current enclosed by the dashed loop is 1. ) The amount of currem enciosed by tne oasneo 1oop is ) The path inicgral of part 2 an ar ar zam pecause une iB fieid is perpendicular to line 2 and line 4 i2 0 ) The path integrai of B dot d3 for partl and part 3 are zero, because the B tieia is perpenaicuiar to line i ana in 13 The path integral of B dot ds for parti is B tumes tengtn The path integral of B dot ás lor pard is zero, because B is neariy zero tnere. 15 o The path imegrai of b dou dsš tor the enture dasined 1oop is e imes, iength ( ) The pain integrai or' C lo roger. dot as ior me entire dashed 100p is rwice or B times iengti. The B field strength due to an ideai soienoià is propornionai to uts curc )The B field strength due to an ideal solenoid will increase if you increase the total number of turns and mak 20 The B rieid strengtn aue to an ideai soienoid wil doubie if you make the soienoid twice iong. ) The B fieid strength due to an ideal solenoid will double if you pack the wires twice dense.
