Dear Mr Ramanujan,

I am a master's student in mechanical engineering .

I have read your literature(On demand manipulation of ferrofluid droplets by magnetic fields)and it was so interesting .So I tried to use your literature to validate my project .But I have some questions about that and I would be grateful if you could tell me:

1.Lenght and width and angle of this channel

2.surface tension coefficient number and contact angle( in Comsol software)

Please let me know how can I solve it.

Yours faithfully
